In specific implementation, the data link group can be the multi-hop data link for including equipment 104,106,108 and/or 110 Group.In this realization method, it can be route from the wireless communication of the first equipment 104 to the 4th equipment 110 by the second equipment 106 (for example, retransmission).In another specific implementation, the data link group can be include equipment 104,106 and 108 Single-hop data link group.4th equipment 110 can not be included in the single-hop data link group, because of the 4th equipment 110 in the range for wireless communication of the first equipment 104 (be known as one and jump range).
First equipment 104 can be configured as offer service (for example, being operated as provider equipment).For example, first sets Standby 104 can be configured as data source operation.First equipment 104 can be to the miscellaneous equipment in the data link group (for example, subscriber device) transmission data.For example, for shared music service, the first equipment 104 can be to the data link group In another equipment send music data.As another example, in order to share social media service, the first equipment 104 can be to Another equipment sending information data, image data, video data or combination thereof in the data link group.As another Example, in order to share game services, the first equipment 104 can be to another equipment sending information number in the data link group According to, score data, image data, video data or combination thereof.The subscriber device can be configured as data sink Operation.
In specific implementation, provider's logic 130 of the first equipment 104, subscriber's logic 134 of the second equipment 106 Or the two can execute " capabilities exchange " in provider's logic 130 to before 106 transmission data 122 of the second equipment.The energy Power, which exchanges, to be executed during the stage in " connection is established " of the communication of NAN 102.In some implementations, the connection is built The vertical stage can be " association " stage of the communication of NAN 102.For example, it includes that association exchanges that Fig. 1, which instantiates the association phase, 112, wherein subscriber's logic 134 of provider's logic 130 of the first equipment 104 and the second equipment 106 can pass through exchange capacity Information 114 and availability information 116 carry out executive capability exchange.Association exchanges 112 and also can indicate that the first of the first equipment 104 leads to Second communication information or the two of letter information, the second equipment 106.For example, first communication information and/or described Two communication informations may include security information (for example, group key or public network key).Although Fig. 1 is instantiated wherein described The realization method of availability information 116 is exchanged during association phase, but in an alternative implementation, it can find window in NAN Availability information 116 is exchanged during mouthful.In other realization methods, the connection establishment stage may include the logical of NAN 102 " negotiation " stage of letter.During the negotiation phase, provider's logic 130 of the first equipment 104 and the second equipment 106 are ordered Family logic 134 can be exchanged by exchanging capability information 114 and availability information 116 come executive capability.In addition to substituting association behaviour Make to execute except negotiation, the negotiation phase can be similar to the association phase.
Although Fig. 1 instantiates the specific implementation that wherein ability information 114 is detached with availability information 116, It replaces in situation, availability information 116 may include in ability information 114.For example, during association, " the ability Exchange " may include multiple parameters, and availability information 116 can be included as additional parameter.As illustrative rather than Restrictive example, availability information 116 can be the individual bits in " availability " field of ability information 114, such as zero Value or 1 value.Alternatively, more than one bit can be used to provide for the more detailed information about availability.For example, available Property information 116 can include multiple bits and the field of corresponding with " always " available state instruction is provided.It illustrates Bright, multiple zero value can indicate special usability status, such as " always " available state.As used in this article, " specially With " availability instruction be so that the particular device will be in the time for being instructed to special availability to the scheduling of particular device Place's monitoring or the communication for otherwise participating in special session or group.In some implementations, as the participant of NAN, Particular device can be participated in during specific time frame and the NAN associated multiple groups or communication session, such as multiple numbers According to link group.In this implementation, for special session or group (such as particular data link group of the NAN) " specially With " availability indicate the particular device will be participated at the time for being instructed to special availability the special session or Group." always " available state is an example of special usability status.As another example, availability information 116 can be with Instruction corresponding with " preference is polled " state is provided.For example, multiple 1 value can indicate " preference is polled " state. As another example, availability information 116 can provide instruction corresponding with " preference transmission trigger frame " state.For example, 0 and 1 combination in the field can indicate " preference transmission trigger frame " state.
Fig. 1 instantiates wherein the first equipment 104 and the second equipment 106 and indicates that two " associated with each other " of NAN 102 set Standby particular exemplary realization method.For example, the pass that NAN 102 is being added in wherein equipment 104, one of 106 can be executed Connection exchanges 112.When equipment 104,106 is being associated with, both equipment 104,106 can indicate or exchange capacity, and indicates to set Whether standby 104,106 be " always " available, or whether equipment 104,106 is available to determine using triggering or polling mechanism Property.For example, if NAN 102 is being added in the second equipment 106, and the second equipment 106 is " always " to can be used at this It is communicated on a NAN 102, then the availability information 116 provided from the second equipment 106 during the association phase can be to hair The second equipment described in poll during data window can be forbidden to the transmitter by penetrating machine (such as first equipment 104) offer The instruction of 106 (as further described herein in relation to Fig. 3).By forbidding poll, it is possible to reduce the message in NAN 102 Transmission business.
As another example, availability information 116 can be provided to transmitter (such as first equipment 104) to the transmitting Machine can forbid waiting for the instruction of the confirmation (ACK) from the second equipment 106, and the confirmation is can be used for the second equipment 106 The confirmation (ACK) of data is received from the transmitter.On the contrary, (such as further being retouched herein in relation to Fig. 3 during paging window State), the transmitter can send the service announcement that the second equipment 105 is identified as to recipient, and can be based on instruction The availability information 116 of availability of second equipment 106 during the data window, to 106 transmission data of the second equipment ( During the data window) without waiting for ACK.The service announcement can be service indication message, also referred to as service indicator, It may include traffic indication map (TIM).If availability information 116 indicates that the second equipment 106 can be used in the data Data are received between window phase, then the second equipment 106 keeps " wake-up " during the data window, rather than is transformed into low-power Operation mode (or operation on another NAN of execution).
As another exemplary example, during association, by the availability information of the equipment offer of such as the second equipment 106 116 can indicate that the equipment is not " always " available, or instruction equipment " preference " quilt " poll " or " preference " hair Trigger frame is sent to determine the availability for receiving data during certain window.For example, in some cases, according to being transformed into Low-power operating mode executes operation on another NAN, and the second equipment 106 is disabled.Equally, availability information 116 Instruction can be provided to the first equipment 104, the instruction is will be by " poll " to provide the finger to availability to the second equipment 106 The instruction shown, or trigger frame will be sent to provide the finger of the instruction to availability to the first equipment 104 to the second equipment 106 Show.In this case, as further described herein, the first equipment 104 can be sent is identified as number by the second equipment 106 According to the service indication message of recipient's (during paging window).As used herein, it is that data " receive by device identification Side " refers to that mark is scheduled as receiving the equipment of data (even if the equipment receives not yet from another equipment Some in the data or any data) instruction.It is set based on the availability information 116 provided by the second equipment 106, first Standby 104 can forbid to 106 transmission data of the second equipment (during data window), until the first equipment 104 determines that second sets Standby 106 availability, such as via poll or trigger frame.
In specific implementation, equipment that the data can be via second wireless channel in the data link group Between send, the second wireless channel is referred to as " data link group " channel.As used herein, " data link group Channel " be for the equipment in corresponding data link group remain for transmitting in advance the message (such as paging message) about shared service with And the specific radio channel of transmission data associated with the service.Logic channel can correspond to data link group channel and One or more sends window.For example, data can be during one or more of transmission windows, via the data link Group channel is sent between the equipment in the data link group.As used herein, described " data link group channel " It is associated with data link group network, and the communication in the data link group network can be in the data link group channel Upper execution.In addition, the data link group channel can be used for shared security information, operation associated and execution routing operations are executed (in multi-hop data link group).
In some implementations, the data link group channel and the NAN communication channels can be and different radio The corresponding different radio channel of frequency band.In specific implementation, the NAN communication channels can be 2.4 gigahertzs (GHz) letter Road, and the data link group channel can be 5GHz channels.In other realization methods, the data link group channel and The NAN communication channels can be identical wireless channel.For example, equipment 104,106,108, one or more of 110 can With via NAN 102 (for example, via described NAN communication channels) and the data link group shared data.In some realization sides In formula, NAN 102 may include multiple data link groups, and each in the multiple data link group can correspond to Different data link group channels.The multiple data link group can correspond to by the distinct device offer in NAN 102 Difference service.In other realization methods, the equipment in the multiple data link group can be via 102 shared datas of NAN. In some implementations, the equipment in the multiple data link group can be during different transmission windows via identical number According to link group Channel Sharing data.
During operation, one of equipment of NAN 102 can generate and send synchronization according to NAN standards or agreement (sync) beacon.For example, third equipment 108 can send the sync beacon via the NAN communication channels.Third equipment Any equipment in a 108 jump range can retransmit the sync beacon so that the sync beacon can be entire It is propagated in NAN 102.Each in equipment 104,106,108 and 110 can receive the sync beacon, and can be based on The sync beacon executes simultaneously operating.For example, equipment 104,106,108,110 can based on receive the sync beacon come Synchronization timing circuit, such as internal clocking.
As described herein, the first equipment 104 can be after executing the simultaneously operating, as going to NAN's 102 The provider equipment of the special services of miscellaneous equipment starts to operate.Provider's logic 130 of first equipment 104 can determine first Multiple logic channels.For example, provider's logic 130 can be based on default data, based on the first equipment 104 user input or Person is based on the two, determines a logic channel more than described first.A logic channel more than described first can correspond to multiple communication letters Road (for example, radio communication channel) and one or more associated transmission windows, as with reference to described in figure 2.Provider's logic 130 can determine multiple available logic channels.For example, the multiple available logic channel can be a logic letter more than first Subset in road, the subset are not used by provider's logic 130 of the first equipment 104 such as to participate in other numbers According in provider's group.
Provider's logic 130 of first equipment 104 can select one or more from the multiple available logic channel A logic channel 150 provides special services.For example, as described herein, provider's logic 130 of the first equipment 104 can be with At least one of logic channel 150 logic channel is selected based on the delay-sensitive degree of the special services.As unrestricted Property example, the special services can be audio streaming services, game services, music provider service or messenger service.
In particular example, game services can have the first delay-sensitive degree, messenger service that can have the second delay Susceptibility, and the first delay-sensitive degree can be higher than the second delay-sensitive degree.The multiple available logic letter The first logic channel in road may include the transmission window of the first quantity, and second in the multiple available logic channel patrols The transmission window that channel may include the second quantity is collected, and second quantity can be higher than first quantity.At this In example, there is the first delay-sensitive degree for meeting specific delays susceptibility threshold in response to the determination game services, Provider's logic 130 of first equipment 104 can select second logic channel to be included in logic channel 150.As Another example has in response to the determination messenger service and cannot be satisfied described the second of the specific delays susceptibility threshold and prolong Provider's logic 130 of slow susceptibility, the first equipment 104 can select first logic channel to be included in logic channel In 150.
Provider's logic 130 of first equipment 104 can generate the first equipment 104 of instruction and can be used for via logic channel 150 message (for example, service advertisement 120) communicated.For example, provider's logic 130 can generate service advertisement 120 with logical Know the availability of the special services.Service advertisement 120 can indicate logic channel 150.For example, service advertisement 120 can wrap Include the list of index corresponding with the logic channel.The index list can be based on mapping data, the mapping number According to each logic channel being mapped to particular index in logic channel 150.The mapping data can be equipment 104,106, One or more of 108 and 110 is addressable.
In specific implementation, the first equipment 104 can provide the special services via basic communication channel.It is described Basic communication channel can correspond to find that window terminates the transmission window of the NAN channels started later in NAN, such as following It is further described relative to Fig. 3 and 4.In specific implementation, service advertisement 120 can not indicate the basic communication letter Road.Subscriber's logic 134 of equipment (such as second equipment 106) assume that in response to receiving service advertisement 120, the first equipment 104 can be used for providing the special services via the basic communication channel, and the base whether is indicated but regardless of service advertisement 120 This communication channel.Logic channel 150 can correspond to complement channel, and the complement channel is also referred to as supplement communication channel.
Provider's logic 130 of first equipment 104 can be during NAN has found window, via the transmitting-receiving of the first equipment 104 Machine 136 sends service advertisement 120 to the equipment (such as the second equipment 106 and third equipment 108) of NAN 102.Equipment 104, 106,108 and/or 110 the NAN channels can be monitored during the NAN has found window.One or more equipment (for example, Second equipment 106 and third equipment 108) it can find that window phase receives service advertisement 120 indirectly in the NAN.
In specific implementation, subscriber's logic 134 of the second equipment 106 can in response to receiving service advertisement 120, It generates and subscribes to message 124.For example, subscriber's logic 134 of the second equipment 106 can be in response to receiving service advertisement 120 simultaneously really Fixed second equipment 106 can be used for being communicated via at least one of logic channel 150, generates and subscribes to message 124.Subscription disappears Breath 124 can either implicitly or explicitly indicate that the second equipment 106 can be used for communicating.Subscriber's logic 134 of second equipment 106 can be with It is sent to the first equipment 104 via the transceiver 136 of the second equipment 106 and subscribes to message 124.
Provider's logic 130 of first equipment 104, which can receive, subscribes to message 124.Provider's logic of first equipment 104 130 can be based on receiving subscribing to message 124, determine that the second equipment 106 can be used for communicating.In specific implementation, subscribe to Message 124 can explicitly indicate that the second equipment 106 can be used for communicating.For example, the value for subscribing to the specific fields of message 124 can be with Indicate whether the second equipment 106 can be used for communicating.In this realization method, provider's logic 130 of the first equipment 104 can be with In response to determining that the specific fields for subscribing to message 124 have particular value (for example, 1), determine that the second equipment 106 can be used for communicating. In an alternative implementation, subscribing to message 124 can impliedly indicate that the second equipment 106 can be used for communicating.In this realization side In formula, provider's logic 130 of the first equipment 104 can subscribe to message 124 in response to receiving, and determine that the second equipment 106 can For communicating.
In specific implementation, provider's logic 130 of the first equipment 104 can be in response to receiving subscription message 124, it is sent to the second equipment 106 and confirms (ACK).In an alternative implementation, provider's logic 130 can not send described ACK.For example, the handshake procedure between the first equipment 104 and the second equipment 106 can receive subscription with provider's logic 130 Message 124, which is used as, to be terminated.
May include the first equipment 104 and the second equipment with each corresponding data link group in logic channel 150 106.In specific implementation, the first equipment 104 can connect from multiple subscriber devices (such as equipment 106,108 and/or 110) It receives and processes subscriptions and reads message.Data link group corresponding with particular logical channel may include the first equipment 104 and using subscribe to message into Each subscriber device of row response.Data link group corresponding with basic communication channel may include the first equipment 104 and utilize The each subscriber device for subscribing to message to respond service advertisement 120.
Each data link group can correspond to particular logical channel.For example, each data link group can correspond to spy Determine communication channel and one or more transmission windows.For example, the data-link associated with the basic communication channel The transmission window that road group can correspond to the NAN communication channels and start at the end that NAN has found window, such as relative to figure 3 further describe.
The equipment for participating in particular data link group can be in one or more of beginning portions of each for sending window Divide and monitors the specific communication channel during (for example, paging window).For example, the first equipment 104 and the second equipment 106 can be During the paging window terminated at the end of NAN has found window, the NAN communication channels are monitored.As another example, it first sets Standby 104 and second equipment 106 can during one or more corresponding paging windows of each sent in windows, monitoring with Each corresponding specific communication channel in logic channel 150.
In specific implementation, the equipment for participating in data link group can be in the corresponding transmission window of one or more During the paging window of at least the first quantity of each, corresponding communication channel is monitored.For example, in logic channel 150 One logic channel can correspond to first communication channel and one or more transmission windows.Subscriber's logic 134 of second equipment 106 Institute can be monitored during the paging window of one or more of at least the first percentages (for example, 50%) for sending window State first communication channel.For example, subscriber's logic 134 of the second equipment 106 can monitor described the during the first paging window One communication channel, and can forbid monitoring the first communication channel during the second paging window.The first paging window Mouth and the second paging window can occur during the identical discovery period or during the different discovery periods.Such as institute herein Reference, " it was found that period " also refers to the time between the end of the first discovery window and next beginning for finding window Section.
In the example illustrated in Fig. 1, provider's logic 130 of the first equipment 104 can be in response to determining the first equipment 104 have the data to be sent for giving the second equipment 106, generating beep-page message 128.Paging message 128 can indicate that first sets Standby 104 have the data to be sent for giving the second equipment 106.For example, paging message 128 can indicate one or more receptions Side, such as the second equipment 106.
Provider's logic 130 of first equipment 104 can be during first sends the first paging window of window, via the One communication channel sends paging message 128.Provider's logic 130 of first equipment 104 can be via the transmitting-receiving of the first equipment 104 Machine 136 sends paging message 128.The first communication channel and the first transmission window can correspond to logic channel 150 In the first logic channel.In specific implementation, paging message 128 may include self-organizing service indication message (ATIM).For example, sending paging message 128 during the ATIM windows at the beginning that can send window described first.
In specific implementation, paging message 128 may include the address column list 160 for indicating the recipient. In some cases, address list 160 can be indicated by traffic indication map (TIM).The TIM can be instruction particular device The bitmap of the no recipient for being data to be sent 122.Each bit in the TIM can correspond to the data link Distinct device in group, and the value of each bit can indicate the corresponding equipment whether be data 122 recipient.It is described Correspondence between the bit of TIM and each equipment can be based on associated identifiers (AID).For example, the second equipment 106 Can be associated with the first equipment 104, and equipment 104,106 can generate and exchange AID.For example, the second equipment 106 Can be associated with the first equipment 104, and the first AID (for example, 2) can be received from the first equipment 104.Equipment 108 and 110 It can be in the AID (for example, be respectively 3 and 4) different from being received during the association of the first equipment 104.The AID can be by equipment 106,108,110 using identifying from the corresponding bit in the TIM that the first equipment 104 receives.For example, since the AID is 2, The second bit of the TIM can correspond to the second equipment 106.In this illustration, the third and fourth bit of the TIM can To correspond respectively to equipment 108 and 110 (the first bit of the TIM can be reserved).
In some implementations, paging message 128 includes the receiver address word for having specific receiver address value 170 Section.Compared to different types of message, the receiver address field with specific receiver address value 170 can be paged to receiving The equipment instruction paging message 128 of message 128 is paging message.In specific implementation, specific 170 quilt of receiver address value It is stored in the memory of equipment 104,106,108 and 110.For example, specific receiver address value 170 can manufactured and produced Period is programmed and stored in the memory of equipment 104,106,108 and 110.Specific receiver address value 170 can be for Each in equipment 104,106,108 and 110 is public.In some implementations, specific receiver address value 170 can With defined in NAN standards or other wireless communication standards.For example, specific receiver address value 170 can by ieee standard, Wi-Fi Alliance specification or the two definition.In other realization methods, specific receiver address value 170 can with equipment 104, 106,108 is related with value determining during 110 operation.As a non-limiting example, specific receiver address value 170 can To be NAN Cluster Identifiers (ID) related with NAN 102.As another unrestricted example, specific receiver address Value 170 can be data link group ID related with the data link group.
After receiving paging message 128, each in equipment 106,108 and 110 can be with processing beep-page message 128 In the part for including the receiver address field, to determine whether paging message 128 is paging message.For example, equipment 106,108 and 110 subscriber's logic 134 can be configured as a part (such as one of header for handling received message Point or other parts), to determine whether received message is paging message.In some implementations, the receiver Location field can be included in the first address field in paging message 128, and equipment 106,108 and 110 can be configured It is processing beep-page message 128 until first address field.In other realization methods, the receiver address field can be with It is different address field, and equipment 106,108 and 110 can be configured as processing beep-page message 128 until the reception Machine address field.Handle received message a part may include:Determine the value of the receiver address field, and will Described value is compared with specific receiver address value 170.If the receiver address field has specific receiver address Value 170, then the received message of the determination of equipment 106,108 and 110 is paging message (for example, paging message 128).If described Receiver address field has the value different from the specific receiver address value 170, then equipment 106,108 and 110 determines institute The message of reception is not paging message.Since a small amount of part of the message received is handled, it is thus determined that the message received Whether it is that paging message can be by rapidly and using than the major part for handling received message or whole less places Resource is managed to execute.
In response to paging message 128 is identified as paging message, one or more of equipment 106,108 and 110 can be with It is sent to the first equipment 104 and confirms (ACK) 180.For example, the second equipment 106, third equipment 108 or the two can be set to first Standby 104 send ACK 180.ACK 180 can be sent by the equipment for not being paged the recipient that message 128 is designated as data 122. For example, third equipment 108 can send ACK 180, even if third equipment 108 is not indicated as the recipient of data 122.Citing Illustrate, third equipment 108 can before the other parts of processing beep-page message 128 in processing beep-page message 128 include institute The part (and ACK 180 can be sent) for stating receiver address field, to determine whether third equipment 108 is indicated as receiving Side.In specific implementation, equipment 106,108 and 110 can be configured as after receiving paging message 128, in short frame Between interval (SIFS) period in send ACK 180.Due to equipment before sending ACK 180 processing beep-page message 128 it is a small amount of Part, therefore processing to the part of paging message 128 and can be happened to the transmission of ACK 180 the SIFS periods It is interior.
In some implementations, the first equipment 104 can receive multiple from the multiple equipment in the data link group ACK 180.In specific implementation, the multiple equipment generates the multiple ACK 180 based on identical Scrambling seeds. In this realization method, 180 waveforms having the same of the multiple ACK, and by as multiplexing in the first equipment It is received at 104.In another specific implementation, the multiple equipment is generated the multiple based on different Scrambling seeds ACK 180.In this realization method, the multiple equipment can send the multiple ACK 180 within the SIFS periods.Due to The multiple ACK 180 is generated and is sent simultaneously based on different Scrambling seeds, and the first equipment 104 may be by institute It interferes caused by stating multiple ACK 180 and the multiple ACK 180 cannot be decoded.In this case, the first equipment 104 can be with The monitoring wireless network during the SIFS periods, to detect transmission energy level corresponding with the multiple ACK waveforms.Work as inspection When measuring the transmission energy level more than threshold value, the transmission energy level can be construed to described more by the first equipment 104 The instruction that a ACK waveforms have been received.
Paging message 128 may include or corresponding to one or more frame.Can in such as 802.11 standards of IEEE or The frame defined in the wireless communication standard of NAN standards.In some implementations, paging message 128 includes management frame or moves Make frame.As unrestricted example, action action frame may include common action frame.In other realization methods, paging message 128 Including service discovery frame (SDF), it is referred to as release of service.The SDF may include attribute 172, and the attribute 172 wraps Include information related with the subset of devices, will be by the type for the business (for example, data 122) that the first equipment 104 is sent and its Its information.Attribute 172 is properly termed as " service announcement attribute " or " paging attribute ".Although the SDF is described as including attribute 172, but in other realization methods, paging message 128 may include other frames, such as the management frame or the action Frame, and other frames may include attribute 172.
Attribute 172 includes being paged list of devices (PDL) 174.PDL 174, which can be identified, to be scheduled as from the first equipment 104 receive the subset of devices of data 122.For example, the first equipment 104 can be configured as during the part for sending window, Equipment transmission data 122 into the subset of devices.In some implementations, address list 160, paging message are substituted 128 include PDL 174.In specific implementation, PDL 174 is indicated by TIM.In another specific implementation, PDL 174 It is indicated by Bloom filters.The Bloom filters be instruction set in member relation without specifically identifying the set In member data structure.In specific implementation, the data structure can be Bit String.The Bloom filters The subset of devices for being scheduled as receiving data 122 can be identified.The Bloom filters can than TIM smaller and use than The less memory spaces of TIM, and therefore with use the TIM as PDL 174 compared with, it is possible to reduce send the Bloom The power that filter is consumed, and the size of paging message 128 can be reduced.Hash function set can be used, described Equipment is designated as to the target of data 122 in Bloom filters.For example, the Bloom filters can be with m bit Bit-array, the m bit is initialized to logic zero value, and the Bloom filters can correspond to hash letter Manifold is closed.In order to which indicating equipment is scheduled as receiving data 122, Bit String corresponding with the equipment can pass through the hash Function set is gathered with generating bit position, and corresponding with bit position set every in the Bloom filters A bit is arranged to 1 value of logic.In specific implementation, the Bit String by the hash function set is to be referred to It is shown as address media access control (MAC) of the equipment of the target of data 122.It can be by being based on corresponding bit string (such as MAC Address) determine corresponding bit position set, and by will in the Bloom filters with bit position set pair The each bit answered is set as 1 value of logic, and miscellaneous equipment is designated as to the target of data 122.In another specific implementation, PDL 174 is indicated by MAC Address list.The each equipment for receiving paging message 128 can be configured as processing PDL 174, with It determines whether the corresponding equipment is included in be scheduled as from the subset of devices that the first equipment 104 receives data 122.
In some implementations, the PDL control fields of attribute 172 include type of service indicator.The type of service Indicator can identify type of service corresponding with data 122.For example, the type of service indicator can be with mark data 122 It is voice data, video data, grouped data or other types of data.In specific implementation, the type of service Indicator can be with service quality (QoS) classification of mark data 122.Multiple type of service indicators can be used to indicate by Dispatch the different types of data being used for transmission.As an example, the first equipment 104, which can have, will be sent to the data link The two kinds of data of the equipment in group.Since the first equipment 104 scheduled the transmission of a plurality of types of data, So paging message 128 includes multiple attributes.For example, if the first equipment 104 has the two types for being scheduled for transmission Data, then paging message 128 include the first attribute and the second attribute.Each in described two attributes may include instruction A kind of type of service indicator being scheduled in the data of the type of transmission (in PDL control fields).For example, If the first equipment 104 may include with the voice data and grouped data, first attribute for being scheduled for transmission Indicate that the type of service indicator of voice data and second attribute may include indicating that the type of service of grouped data refers to Show symbol.
In addition, the PDL control fields can indicate the type of PDL 174.For example, the PDL with the first value is controlled The bit set of field processed can indicate that PDL 174 is indicated by TIM, the sets of bits of the PDL control fields with second value Conjunction can indicate that PDL 174 is indicated by Bloom filters, and the bit set of the PDL control fields with third value It can indicate that PDL 174 is indicated by MAC Address list.In addition, the bit set of the PDL control fields with the 4th value can New public packet key (CGK) corresponding with the data link group has been generated with instruction.If the PDL control fields Bit set there is the 4th value, then the MAC Address for generating the equipment of the CGK is included in PDL 174.The CGK can be with Equipment 104,106,108 and 110 is enable to execute wireless communication via the data link group.For example, the CGK can be used The message sent between the equipment of encryption and decryption in the data link group.In some implementations, attribute 172 is gone back Including paging control field 176.Paging control field 176 can indicate the quantity for the PDL being included in paging message 128.It seeks Control field 176 is exhaled to also can indicate that it is multi-case data or unicast data to be scheduled for the data 122 of transmission.With reference to figure 11 Attribute 172 is described with 12 and pages the additional detail of control field 176.
In equipment 106,108 and 110 each can be based on the TIM (address list 160) in corresponding bit or Based on the PDL 174 received from the first equipment 104, determine whether it is scheduled as receiving data 122.For example, the second equipment 106 can determine that the second equipment 106 is scheduled as receiving data 122 based on the second bit of the TIM with logical value 1, And equipment 108 and 110 can have logic zero value based on the third and fourth bit and determine respectively equipment 108 and 110 not by It is scheduling to receive data 122.As another example, the second equipment 106 can determine 106 quilt of the second equipment based on PDL 174 It is scheduling to receive the data, the PDL 174 can be TIM, Bloom filter or MAC Address list.Therefore, it second sets Standby 106 can be maintained at active operation mode during the remainder of the first transmission window.The remainder can be with Including data transmission window.For example, subscriber's logic 134 of the second equipment 106 can be during the data transmission window Monitor the first communication channel.In specific implementation, subscriber's logic 134 of the second equipment 106 (or the first equipment 104 provider's logic 130) channel of the transceiver 136 of the second equipment 106 (or first equipment 104) can be changed to it is described First communication channel, to monitor the first communication channel during the data transmission window.
In specific implementation, subscriber's logic 134 of the second equipment 106 can be sought based on determining second equipment 106 Message 128 is exhaled to be designated as the recipient of the data 122 from the first equipment 104, to first during the data transmission window Equipment 104 sends trigger frame 182.Trigger frame 182 can indicate that subscriber's logic 134 of the second equipment 106 is ready to receive data 122.For example, trigger frame 182 can indicate that the second equipment 106 is scheduled as being in activity operations mould during the transmission window Formula.In specific implementation, power-save poll (PS-POLL) message can be used as trigger frame 812 to operate.In specific implementation In mode, subscriber's logic 134 of the second equipment 106 can be in the beginning of the data transmission window (for example, confirming window Mouthful) during, send the PS-POLL message via the first communication channel.In another specific implementation, service quality Empty (QoS_NULL) message can be used as trigger frame 182 to operate.In specific implementation, the type of service of trigger frame 182 can To be arranged to high-priority service type.For example, QoS classifications corresponding with trigger frame 182 can be set to high priority Classification, such as voice data.By setting the type of service to high priority type, trigger frame 182 can increased The possibility sent, to reduce or eliminate since trigger frame is queued being transmitted and wirelessly until higher priority Network become the free time be used to send the trigger frame and caused by postpone.In specific implementation, in addition to paging message 128 Except, the second equipment 106 can receive the second paging message from distinct device (not shown).In this realization method, second Equipment 106 can give 182 multicast of trigger frame to the first equipment 104 and distinct device.In this manner it is achieved that if equipment is scheduled To receive business from multiple equipment, then multicast trigger frame can be sent to the multiple equipment.It can be with using multicast trigger frame The quantity for reducing trigger frame, to reduce the congestion of wireless network.
In specific implementation, equipment 104,106,108 and 110 can be configured as execution competition mitigation technique to subtract Few ACK, trigger frame or conflict between the two.Mitigate to execute competition, each in equipment 104,106,108 and 110 It may include, store and/or safeguard one or more fallback counters.One or more of fallback counters can be by equipment 104,106,108 and 110 using determining the hair when initiated during paging window (or send window) to ACK or trigger frame It send.For example, after receiving paging message 128, the second equipment 106 and third equipment 108 can be by fallback counters It is set as the value extracted at random from being uniformly distributed on interval [0, CW], wherein CW is contention window parameter.In some realizations In mode, CW has particular value, such as pre-programmed values or the value by wireless communication standard setting.In other realization methods, such as Described further herein, CW is the length based on the paging window.In other realization methods, distribution parameters (ratio Such as contention window parameter or another parameter) by equipment 104,106,108, one or more of 110 using distributing ACK, Or trigger frame is indicated by the paging message.For example, equipment 104,106,108,110 is in PDL 174 or in address list 160 In sequence can correspond to the CW for each equipment 104,106,108,110.For example, with address list 160 The associated equipment in first position can use the first CW, and equipment associated with the second position in address list 160 can be with Use the 2nd CW (wherein, the 2nd CW is different from the first CW) etc..If the fallback counter at the second equipment 106 Zero is reached, then the second equipment 106 sends ACK 180 to the first equipment 104.If the fallback counter at third equipment 108 arrives Up to zero, then third equipment 108 sends ACK 180.In some implementations, if in the second equipment 106 and third equipment 108 One sent ACK 180, then miscellaneous equipment does not send ACK 180.Alternatively, the second equipment 106 and third equipment 108 can With the different random value based on the fallback counter come in different time transmission ACK 180.The fallback counter can be by It is used according to described above for sending the same way of trigger frame 182.In other realization methods, more than one rollback Counter can be used to further be randomized the time for sending ACK or trigger frame.It is described further herein to execute competition The additional detail of mitigation and other realization methods.
In specific implementation, before sending paging message 128, the first equipment 104 can be to being scheduled as from The equipment that the subset of devices that one equipment 104 receives data includes sends the first request and sends (RTS) message 184.For example, first Equipment 104 can send the first RTS message 184 before sending paging message 128 to the second equipment 106.In response to receiving First RTS message 184, the second equipment 106 can send the first clear to send (CTS) message 186 to the first equipment 104.First CTS message 186 can be sent within short interFrameGap (SIFS) period for receiving the first RTS message 184.The data link group Miscellaneous equipment can detect the first RTS message 184, the first CTS message 186 or the two via wireless network, and it is described its Its equipment can be forbidden in response to detecting the first RTS message 184, the first CTS message 186 or the two in special time period Via the wireless network transmission data.Therefore, the first RTS message 184, the first CTS message 186 or the two can be that paging disappears Transmission " removing " described wireless network of breath 128.In response to receiving the first CTS message 186, the first equipment 104 can be to institute The equipment stated in data link group sends paging message 128.In specific implementation, paging message 128 may include having Identify the second receiver address of the value of the second equipment 106.In another specific implementation, paging message 128 may include Multicast message, the multicast message include the second receiver address for having multicast address.
In some cases, the second equipment 106 may be such as due to the miscellaneous equipment of the data link group has to institute The control of wireless network is stated, the first CTS message 186 cannot be sent within the SIFS periods.If the first equipment 104 is described The first CTS message 186 is not received by the SIFS periods, then the first equipment 104 can include not to the subset of devices The 2nd RTS message 188 is sent with equipment.For example, the first equipment 104 can be before sending paging message 128, to third equipment 108 send the 2nd RTS message 188 (if third equipment 108 is included in the subset of devices).In response to receiving second RTS message 188, third equipment 108 can send the 2nd CTS message 190 to the first equipment 104.In response to receiving the 2nd CTS Message 190, the first equipment 104 can send paging message 128 to the equipment in the data link group.In some realization methods In, data 122 can be multi-case data.In these realization methods, paging message 128 may include multicast indicator.For example, Paging message 128 may include the specific fields that designation date 122 is unicast data or multi-case data.Multi-case data can wrap The data of multiple equipment will be concomitantly sent to by including, and may include broadcast data.In these realization methods, first sets Standby 104 can select recipient of any equipment as the first RTS message 184 in the data link group.
Provider's logic 130 of first equipment 104 can receive (the institute of trigger frame 182 during the data transmission window State PS-POLL message or the QoS_NULL message).In response to receiving trigger frame 182, the provider of the first equipment 104 patrols The second equipment can be sent to via the first communication channel during the data transmission window by data 122 by collecting 130 106.In the example illustrated in Fig. 1, paging message 128 further includes to the availability for next N number of logic channel 164 Or the instruction 162 of unavailability.As described further below, the special services that the first equipment 104 is provided are being subscribed to One or more neighbor devices (such as second equipment 106) can determine whether to execute one or more behaviour based on instruction 162 Make.
In specific implementation, the instruction 162 that paging message 128 includes can indicate to be directed to the first equipment 104 The instruction of the unavailability of next N number of logic channel 164.It is, the paging message 128 illustrated in Fig. 1 can indicate It is noticed via " current " paging (business) of " current " logic channel, and the instruction of unavailability 162 can be indicated in institute State " future " logic followed after " current " logic channel in the index of the logic channel of particular data link group Channel, as further described below in relation to Fig. 2.It is described to patrol although being referred to as " current " and " future " logic channel Collect any logic channel that (reference) is quoted in the index that channel can be the logic channel.For example, described " current " Logic channel also refers to the first logic channel quoted in the index of the logic channel, and " future " logic is believed Road also refers to the one or more logic channels followed after first logic channel in the index, such as As unrestricted example, the second logic channel and third logic channel.For example, " current " logic channel can be with It indicates the first logic channel in the index, and indicates that 162 can specify the first equipment 104 to be patrolled for next four Channel (that is, N=4) is collected to be disabled.In this illustration, from the first logic channel to the index in the index The 5th logic channel, the first equipment 104 can be all disabled, and " future " logic channel refers to described Two logic channel is to the 5th logic channel.
In response to receiving to not available instruction 162, subscriber's logic 134 of the second equipment 106 can forbid monitoring institute State next N number of logic channel 164 in the logic channel 150 of particular data link group.In some cases, the second equipment 106 can reduce power consumption by being maintained in low-power operating mode, and forbid waking up described following to monitor N number of logic channel 164 (including paging window).Alternatively, the second equipment 106 can execute it is associated with another data link group One or more operations.For example, if the second equipment 106 subscribes to multiple providers, the second equipment 106 can be based on and institute The intersection of each associated unavailability in multiple providers is stated, schedule power saves operation or concurrent operations.As Illustrative but unrestricted example, the second equipment 106 can subscribe to Liang Ge providers (for example, the first equipment 104 and another Equipment).According to when described two provider equipments all indicate that unavailability, the second equipment 106 can be saved with schedule power and be grasped Work or concurrent operations.
In another implementation, the instruction 162 that paging message 128 includes can be indicated to 104 needle of the first equipment Instruction to the availability of next N number of logic channel 164.It is, the paging message 128 illustrated in Fig. 1 can indicate It is noticed via the paging (business) of the first logic channel, and the instruction of availability 162 can be indicated in the specific data The other logic channels followed after first logic channel in the index of the logic channel of link group are such as following opposite It is further described in Fig. 2.As illustrative but unrestricted example, first logic channel can indicate the index In the first logic channel, and indicate 162 can specify the first equipment 104 for next four logic channels (that is, N =4) it is available.In this illustration, from the first logic channel in the index to the 5th logic letter in the index Road, the first equipment 104 can be all available.
In response to receiving the instruction 162 to availability, subscriber's logic 134 of the second equipment 106 can be to the first equipment 104 send confirmation.The confirmation can be PS-POLL message.If the first equipment 104 is from each in the subscriber device Confirmation is received, then the first equipment 104 can not send service announcement in next N number of logic channel 164.It takes and generation It, the first equipment 104 can be with transmission data business.Therefore, to the availability for next N number of logic channel 164 Instruction 162 can reduce paging message and the associated quantity for confirming (ACK), and can allow in different time frequency Growth data transmission on block (for example, next N number of logic channel 164).Pass through notice " future " availability, the first equipment Service announcement can not included in the paging window during the period corresponding with subsequent logic channel by 104.Such as phase Fig. 9 is further described, would ordinarily be used at least some paging windows of service announcement can be substituted for sending number According to business.It is, for include paging window (PW) partly with the transmission window of data portion, with the PW partly it is associated At least part of time can be used for data transmission.
In specific implementation, instruction 162 can identify availability via the first bit (such as 1), and can be through Unavailability is identified by the second bit (such as 0).As illustrative but unrestricted example, in order to indicate the first equipment 104 It is available for next N number of logic channel 164, the instruction may include [1, N], wherein N is integer value. In order to indicate that the first equipment 104 is disabled for next N number of logic channel 164, the instruction may include [0, N], wherein N is integer value.Nevertheless, it will be understood that mark availability or the alternative of unavailability can also be used Method.
Therefore, Fig. 1 is instantiated during the association phase of the communication of the NAN, and equipment can exchange availability information, institute Instruction of the availability information offer to the availability communicated during follow-up data window is provided.Provided that quotient's equipment will be ordered Family equipment is identified as the recipient of data, then the provider equipment can be sent including the subscriber device is identified as data Recipient TIM paging message, and the provider equipment can be based on indicating the subscriber device in data window The availability information of the availability of period, to the subscriber device transmission data during the data window, without etc. Wait for ACK.For example, if the second equipment 106 is identified as the recipient of data by the first equipment 104, the first equipment 104 can be with base The paging message including TIM is sent in availability information 116, without waiting for ACK.In addition, in response to including being ordered described in mark The paging message of the service indicator of family equipment, the subscriber device can be forbidden providing ACK to the provider equipment.Cause This, the availability information 116 provided during the association phase of the communication of NAN 102 can cause in NAN 102 Polling message business and ACK message business reduction.
Fig. 1 also illustrates that the equipment in the data link group of NAN 102 can be provided via paging message and is connect down to being directed to The availability of the N number of logic channel come or the instruction of unavailability.In some cases, the instruction of availability can be allowed to carry Forbid offer business logical during the part paging window (PW) for subsequently sending window for quotient's equipment (such as first equipment 104) It accuses, but alternatively executes data transmission.As a specific example, during the paging window for sending window first, the offer Quotient's equipment can send paging message to one or more of data link group equipment.In this illustration, it is based on coming From the instruction to availability of the certain subscriber equipment of the data link group, sends window second and (sent described first After window) during, the provider equipment can be to the certain subscriber equipment transmission data business, without described Service announcement is sent during the paging window of second transmission window.In some implementations, the provider equipment can be Described in being sent during the part other than described second sends the data window part of window in the second transmission window Data service.For example, the provider equipment can send window during paging window portion or described second During triggering window portion, at least part of the data service is sent.
In other situations, subscriber device (such as second equipment 106) can be allowed to forbid supervising the instruction of unavailability Survey subsequent logic channel.It replacing, the subscriber device may switch to low-power operating mode (for example, suspend mode), Or execute operation associated with other data link groups.In some implementations, it is being transformed into low power operational mode Before, the subscriber device determines whether the miscellaneous equipment with subscriber device equity is disabled.For example, the subscriber Equipment can be with two equipment equities (such as via operation associated or negotiation), and if described two equipment are all not Available, then the subscriber device may switch to the low-power operating mode.Fig. 1 also illustrates the data-link of NAN 102 The equipment of Lu Zuzhong can receive paging message, such as paging message 128, and the paging message includes with specific receiver The receiver address field of location value 170.Use specific receiver address value 170 that can make the equipment for receiving paging message 128 Paging message 128 can be identified by the part including the receiver address field in processing beep-page message 128 For paging message.Less processing can be required than the major part or whole of processing beep-page message 128 by handling the part Resource can be performed faster.
With reference to figure 2, the exemplary table of instantiation logic channel is shown and is generally designated as 200.Table 200 includes NAN data link (NDL) index column 204, channel number row 206 and complement channel offset column 208.In specific implementation, Table 200 can be determined according to NAN standards or agreement.
Every a line of table 200 can correspond to particular logical channel.For example, row 210 can correspond to the first logic letter Road, for example, Fig. 3 basic communication channel 306.Row 210 can indicate the first index (for example, 0), first communication channel (for example, Communication channel 6) and the first complement channel offset (for example, 1).In specific implementation, service advertisement 120 may include described First index is to indicate the first logic channel in logic channel 150.In an alternative implementation, if first index pair Basic communication channel described in Ying Yu, then service advertisement 120 can not include first index.
In specific implementation, provider's logic 130 of the first equipment 104, subscriber's logic 134 of the second equipment 106 Or first complement channel can be deviated (for example, 1) and be multiplied by certain number (for example, 16) to determine that complement channel is inclined by the two It moves (for example, 16 TU).As described with reference to fig. 1, provider's logic 130 of the first equipment 104, second equipment 106 are ordered Family logic 134 or the two can be deviated based on the complement channel is finding it is described that window starts when to start later to determine The transmission window of first logic channel.
Row 212 can correspond to the first complement channel, such as the first complement channel 308 in Fig. 3.Row 212 can indicate First index (for example, 3), first communication channel (for example, communication channel 36), the first complement channel offset (for example, 2) and second Complement channel deviates (for example, 18).Row 214 can correspond to the second complement channel, such as the second complement channel 310 in Fig. 3. Row 214 can indicate that the second index (for example, 13), the second communication channel (for example, communication channel 149), the second complement channel are inclined Move (for example, 9) and third complement channel offset (for example, 25).
Each complement channel offset can indicate and the associated transmission window of corresponding complement channel.In specific implementation In, as described with reference to fig. 1, provider's logic 130 of the first equipment 104 can select first complement channel and described Second complement channel is included in logic channel 150.In this implementation, service advertisement 120 may include first rope Draw and second index.

With reference to figure 3, sequence diagram is shown and is generally designated as 300.In specific implementation, sequence diagram 300 can be with Corresponding to the operation of the specific implementation of the system 100 of Fig. 1.Sequential shown in Fig. 3 and being illustrative for property of operation rather than It is restrictive.In other realization methods, additional or less operation can be executed, and the sequential can be different 's.
Sequence diagram 300 includes corresponding to NAN communication channels 304, basic communication channel 306, the first complement channel 308 and the The total time axis 302 of two complement channels 310.Therefore, multiple supplement communication channels can be used for transmission data.In replaces realization side In formula, single supplement communication channel can be used, or more than two supplement communication channel can be used.
As shown in timing diagram 300, the first discovery window 312 and second finds that window 314 can correspond to NAN communication letters Road 304.As described with reference to fig. 1, it is found that window 312,314 can be reserved for equipment 104,106,108 and 110 to be used for Execute the period for finding operation and simultaneously operating corresponding with NAN 102.
First discovery window 312 may begin at time t1 and can end at time t2 at and the second discovery Window 314 may begin at time t17 and end at time t18.It was found that window 312,314 having the same can be sent out Existing window duration.For example, period between time t1 and time t2 can between time t17 and time t18 when Between section it is identical.The discovery window duration can be determined according to NAN standards or agreement.It is continuous find window (such as First discovery window 312 and second find window 314) between period be properly termed as find the period 316.In specific implementation side In formula, according to NAN standards or agreement, it is found that the duration of period 316 can be 500 chronomeres (TU).Such as IEEE Described in 802.11-2012 specifications, each TU can correspond to 1024 microseconds (μ s), and 500TU can correspond to about 512ms.
During first finds window 312, service advertisement 120 can be sent via NAN communication channels 304.Such as with reference to figure 1 Described, advertising service 120 can indicate logic channel 150.In the example of fig. 3, logic channel 150 may include first Complement channel 308 and the second complement channel 310.Believe for example, provider's logic 130 of the first equipment 104 can be communicated via NAN Road 304 sends service advertisement 120, to notify the service provided by the first equipment 104.For example, service advertisement 120 can refer to Show with the first complement channel 308 and the offset 318 of at least one complement channel (for example, the channels offset 2 in the row 212 of table 200 With 18) corresponding NAN data link group index.In addition, service advertisement 120 can indicate and the second complement channel 310 and at least One complement channel deviates the corresponding NAN data link group of 320 (for example, channels offsets 9 and 25 in the row 214 of table 200) Index.As described with reference to fig. 1, subscriber's logic 134 of the second equipment 106 can be passed through in response to receiving service advertisement 120 It is sent by NAN communication channels 304 and subscribes to message 124.
Basic communication channel 306 can correspond to NAN communication channels 304 discovery window (such as find 312 He of window 314) terminate the transmission window of NAN communication channels 304 started later.For example, as following reference chart 4 will be described with, Basic communication channel 306 can correspond to the first transmission window 322 started after the first discovery window 312.Fig. 3 illustrate with It may begin at t2, and can end at t4 with the first transmission window 322 after the first discovery window 312.Though So be not shown in figure 3, but basic communication channel 306 be also can correspond to follow second find after window 314 can Window is sent to start from second at t18.
Each transmission window associated with basic communication channel 306 may include paging window and data transmission window. Find that the first transmission window 322 after window 132 may include the first paging window 324 and first first for example, following Data transmission window 326.As used herein, include the time of paging window and data window (or data transmission window) Section can be referred to as sending window, TX windows, data transmission window or NAN DL times block (NDL-TB).First paging Window 324 may begin at t2, and can end at t3.First data transmission window 326 may begin at t3, and And it can end at t4.Although in addition, not illustrated in the example of Fig. 3, the hair after finding window 314 second is followed It can also includes paging window (starting from t18) and data transmission window to send window.Page duration, the data hair of window It send the duration of window, send the duration (for example, 128 chronomeres (TU), 256 TU or 512 TU) of window Or combination thereof can be determined according to NAN standards or agreement.
As further described below in relation to Fig. 5 and Fig. 7, the first complement channel 308 can correspond to the first transmission window Mouth 328 and second sends window 330.For example, at least one complement channel offset 318 can indicate NAN find window (such as First discovery window 312) start after deviate the transmission window that starts of 318 corresponding periods at least one complement channel Mouthful.In the specific implementation illustrated in figure 3, the first complement channel 308 can correspond to multiple offsets, the multiple offset Indicate multiple transmission windows during each discovery period (for example finding period 316).In an alternative implementation, the first supplement Channel 308 can correspond to individually deviate, the single transmission window during single offset instruction each discovery period.
Associated with the first complement channel 308 first sends window 328 can be after first finds that window 312 terminates Start.For example, the first transmission window 328 may begin at time t5, and can end at time t7.Time t5 can be with A period of time after timet occurs, and the period corresponds to the first offset of at least one complement channel offset 318 (such as 2).Associated with the first complement channel 308 second sends window 330 can be after the first transmission window 328 terminates Start.For example, the second transmission window 330 may begin at time t11, and can end at time t13.Time t11 A period of time that can be after time t 5 occurs, and the period corresponds to the second of at least one complement channel offset 318 It deviates (for example, 18).
It may include paging window and data transmission window that each of first complement channel 308, which sends window,.For example, first It may include the first paging window 332 and the first data transmission window 334 to send window 328.As another example, it second sends Window 330 may include the second paging window 336 and the second data transmission window 338.First paging window 332 may begin at At time t5, and it can end at time t6.First data transmission window 334 may begin at time t6, and can To end at time t7.Second paging window 336 may begin at time t11, and can end at time t12. Second data transmission window 338 may begin at time t12, and can end at time t13.Paging window continues Time, the duration of data transmission window or the two can be determined according to NAN standards or agreement.
As further described below in relation to Fig. 6 and Fig. 8, the second complement channel 310 can correspond to the first transmission window Mouth 340 and second sends window 342.For example, at least one complement channel offset 320 can indicate NAN find window (such as First discovery window 312) start after deviate the transmission window that starts of 320 corresponding periods at least one complement channel Mouthful.In the specific implementation illustrated in figure 3, the second complement channel 310 can correspond to multiple offsets, the multiple offset Indicate multiple transmission windows during each discovery period (for example finding period 316).In an alternative implementation, the second supplement Channel 310 can correspond to individually deviate, the single transmission window during single offset instruction each discovery period.
Associated with the second complement channel 310 first sends window 340 can be after first finds that window 312 terminates Start.For example, the first transmission window 340 may begin at time t8, and can end at time t10.Time, t8 could With after timet a period of time occur, the period correspond at least one complement channel offset 320 first partially It moves (such as 9).Associated with the second complement channel 310 second, which sends window 342, to send 340 end of window first After start.For example, the second transmission window 342 may begin at time t14, and can end at time t16.Time T14 can occur for a period of time after time t 8, and the period corresponds to the second of at least one complement channel offset 320 It deviates (for example, 25).
It may include paging window and data transmission window that each of second complement channel 310, which sends window,.For example, first It may include the first paging window 344 and the first data transmission window 346 to send window 340.As another example, it second sends Window 342 may include the second paging window 348 and the second data transmission window 350.First paging window 344 may begin at At time t8, and it can end at time t9.First data transmission window 346 may begin at time t9, and can To end at time t10.Second paging window 348 may begin at time t14, and can end at time t15. Second data transmission window 350 may begin at time t15, and can end at time t16.Paging window continues Time, the duration of data transmission window or the two can be determined according to NAN standards or agreement.
As described with reference to fig. 1, in the paging window of basic communication channel 306, the paging window of the first complement channel 308 During the paging window of mouth and/or the second complement channel 310, provider's logic 130 of the first equipment 104 can be logical via NAN Channel 304, the first complement channel 308, the second complement channel 310 or combination thereof are believed to send paging message 128.In addition, As described with reference to fig. 1, provider's logic 130 of the first equipment 104 can be sent via the data of basic communication channel 306 The data transmission window of window, the data transmission window of the first complement channel 308 and/or the second complement channel 310 sends number According to 122.
In specific implementation, paging message 128 may include to for the unavailable of next N number of logic channel The instruction of property.In this case, subscriber's logic 134 of the second equipment 106 can forbid monitoring the particular data link group Logic channel 150 next N number of logic channel.In some cases, the second equipment 106 can be by being maintained at low work( Power consumption is reduced in rate operation mode, and forbids waking up to monitor next N number of logic channel.Alternatively, the Two equipment 106 can execute one or more operations associated with another data link group.In some cases, if second Equipment 106 subscribes to multiple provider equipments, then the second equipment 106 can be based on each from the multiple provider equipment Unavailability intersection, schedule power save operation and/or concurrent operations.
In another implementation, paging message 128 may include to for next N number of logic channel can With the instruction of property.Second equipment 106 can be received by confirming to the availability for next N number of logic channel Instruction, the first equipment 104 is responded.As unrestricted example, the second equipment 106 can disappear via PS-POLL Breath is responded.If the first equipment 104 receives confirmation from each subscriber device, the first equipment 104 can not be other Service announcement is sent in logic channel.It replaces, the first equipment 104 can be with transmission data business.It is also possible to reduce paging The quantity of message (such as service announcement and confirmation) in window.
Therefore, in some cases, the first equipment 104 and/or the second equipment 106 can be by being based in sequence diagram 300 The time sequence window of illustration executes operation to reduce power consumption.For example, if the paging message 128 from the first equipment 104 wraps The instruction to the unavailability for next N number of logic channel is included, then the second equipment 106 can forbid connecing down described in monitoring The N number of logic channel come.In some cases, the second equipment 106 can be reduced by being maintained in low-power operating mode Power consumption, and forbid waking up to monitor next N number of logic channel.In other situations, when subscriber device When received instruction to the availability to provider equipment in N number of logic channel, it is possible to reduce the message in paging window Quantity.
With reference to figure 4, with Fig. 3 total time axis 302 the corresponding sequence diagram of specific part be shown and be generally designated as 400.In specific implementation, sequence diagram 400 can correspond to the operation of the specific implementation of the system 100 of Fig. 1.Fig. 4 Shown in sequential and being illustrative for property of operation and not restrictive.In other realization methods, it can execute additional Or less operation, and the sequential can be different.
As discussed in relation to figure 1, Fig. 4 instantiates the first paging window wherein associated with basic communication channel 306 Mouth 324 includes the particular example of paging message 128.In this case, provider's logic 130 of the first equipment 104 can be through Paging message 128 is sent by NAN communication channels 304.
In specific implementation, paging message 128 may include to for next N number of logic channel not The instruction of availability.With reference to figure 1, the instruction 162 that paging message 128 includes can be indicated to the first equipment 104 for described The instruction of the unavailability of next N number of logic channel 164.As relative to described in Fig. 2, in response to paging window first The instruction 162 to unavailability is received during mouth 324, subscriber's logic 134 of the second equipment 106 can forbid monitoring the spy Fixed number is according to next N number of logic channel 164 in the logic channel 150 of link group.In some cases, the second equipment 106 can reduce power consumption by being maintained in low-power operating mode, and forbid waking up described following to monitor N number of logic channel 164.Alternatively, the second equipment 106 can execute one or more behaviour associated with another data link group Make.
As illustrative example and not restrictive, subscriber's logic 134 of the second equipment 106 can forbid monitoring following Four logic channels (that is, N=4).With reference to figure 3, the second equipment 106 can forbid first paging window 332 (it starts from Time t5 and end at time t6) during monitor the first complement channel 308, forbid first paging window 344 (it starts from Time t8 and end at time t9) during monitor the second complement channel 310, forbid second paging window 336 (it starts from Time t11 and end at time t12) during monitor the first complement channel 308, and forbid second paging window (it is opened Start from time t14 and end at time t15) the first complement channel 308 of period monitoring.
As another example, subscriber's logic 134 of the second equipment 106 can forbid monitoring next five logic channels (that is, N=5).With reference to figure 3, the second equipment 106 can forbid first paging window 332 (it starts from time t5 and terminates In time t6) during monitor the first complement channel 308, forbid first paging window 344 (it starts from time t8 and terminates In time t9) during monitor the second complement channel 310, forbid second paging window 336 (it starts from time t11 and ties Beam is in time t12) during monitor the first complement channel 308, and forbid second paging window (it starts from time t14 simultaneously And end at time t15) the first complement channel 308 of period monitoring.Although in addition, being not shown in figure 3, the second equipment 106 can forbid monitoring the first complement channel 308 during the first paging window after being happened at the second discovery window 314. It is, the first equipment 104 can provide to for illustrated in Fig. 3 find the period 316 after other discovery period phases The instruction of the unavailability of associated other logic channels.
In another implementation, paging message 128 may include to for next N number of logic channel can With the instruction of property.With reference to figure 1, it is included in the instruction 162 in paging message 128 and indicates to connect down the first equipment 104 for described The instruction of the availability of the N number of logic channel 164 come.First equipment 104, which can wait for receiving from subscriber device, to be confirmed, described true Recognize and indicates to receive the instruction to the availability.Second equipment 106 can be received described following to being directed to by confirmation N number of logic channel availability instruction, the first equipment 104 is responded.As non-limiting example, the second equipment 106 can be responded via PS-POLL message.In response to receiving confirmation from each of described subscriber device, first sets Standby 104 can not send service announcement in other logic channels.It replaces, the first equipment 104 can be with transmission data business.
In some cases, the second equipment 106 can indicate the single subscriber of the service provided by the first equipment 104. In this example, if the first equipment 104 is interior from the second equipment in paging window associated with basic communication channel 306 324 106 receive confirmation (such as PS-POLL message), then the first equipment 104 can forbid in next N number of logic channel Middle transmission service announcement.
As illustrative example and not restrictive, the first equipment 104 can be provided to being directed to next four logics letter The instruction of the availability in road (that is, N=4).In this case, if the first equipment 104 is set in paging window 324 from second Standby 106 receive the confirmation, then the first equipment 104 can forbid with the first complement channel 308 and the second complement channel 310 Service announcement is sent in associated subsequent pages window.On the contrary, the first equipment 104 can be in the paging window for subsequently sending window Transmission data 122 in oral area point, transmission data 122 in the data window part of window is sent rather than just supervention in the rear. For example, the first paging window 332 and the first data that the first equipment 104 can send window 328 first send window Transmission data 122 in mouth 334.According to the data volume to be sent for giving the second equipment 106, the first equipment 104 can be with second The first of complement channel 310 sends window 340 associated first and pages window 344, the second hair with the first complement channel 308 It send window 330 associated second to page window 336 and to send window 342 with the second of the second complement channel 310 associated Transmission data 122 in second paging window 348.

With reference to figure 9, the exemplary diagram 900 for sending window (TW) 902 is instantiated.Fig. 9 instantiates transmission window 902 The paging part 904 separated by paging window edge (PWB) 908 and data portion 906.Paging part 904 can be paging Window and data portion 906 can be data windows.During paging part 904, data source can send paging message. For example, the first equipment 104 of Fig. 1 can send the paging message 128 of Fig. 1.In some cases, during paging part 904, The data source can receive from data sink (such as second equipment 106 of Fig. 1) and trigger message, described in the triggering message instruction Data sink is ready to receive data.The data portion 906 for sending window 902 can be used for transmission/reception data, such as Fig. 1 Data 122.In some cases, data sink can send triggering message during data portion 906, and can wait pending datas Transmission.
In some cases, it may be difficult to which prediction sends the size of the paging part 904 of window 902.For example, in number In the case of in link group there are the transmitter of relatively large amount, relatively large paging window may be it is appropriate, so as to for Each of described transmitter provides chance to send service announcement.It is, if sending the paging part 904 of window 902 Too small, then some in the transmitter may not be able to send service announcement.In some cases, this may lead to not fully profit With the data portion 906 for sending window 902, because only industry can be sent during paging part 904 in the transmitter The subset of business notice being capable of transmission data.In contrast, in data link group there are in the case of the transmitter of relatively small amount, Relatively large paging window may cause to underuse.It is, if the paging part 904 for sending window 902 is too big, Each of described transmitter can send service announcement with enough time and receive associated ACK, and page The remainder of part 904 can be used for data transmission.Therefore, it is expected that, using such PWB, it is sufficiently large with Just it provides chance for each transmitter and sends service announcement, but be small enough to reduce and may be alternatively used in data transmission Potential free time.
In some cases, paging window size can be fixed and appointed.It is, PWB 908 can consolidate At specific time after being scheduled at the beginning of sending window 902.In this case, equipment can be restricted to described Paging message is sent during paging window, and after data transmission can occur only at the paging window.However, this Scheme may cause a part for the paging window to remain unused.For example, including relatively small amount in data link group When subscriber device, described paging a part of of window can remain unused.It is, in service announcement and associated In the case of ACK is completed before PWB 908, the paging window can not be fully utilized.Send window 902 Paging part 904 in remaining time can be alternatively for data transmission.In addition, be not recognized as the recipient of data One or more equipment can keep waking up and consuming power to continue to monitor particular logical channel.
In other situations, the paging window size can be fixed, but the size is not that unification is specified, But it is alternatively determined in the NAN (such as NAN 102 of Fig. 1).For example, anchor point device can be based on the big of NAN clusters It is small come determine it is described paging window size.As another example, service origination side can determine the paging for special services The size of window, and can be based on the special services customer count and/or using same logic channel other clothes The quantity of business and equipment is adapted to the size of the paging window.
In some implementations, send window 902 paging part 904 size can be based on data source quantity, Quantity, data service rate or the combination thereof of data sink is adjusted.During sending the paging part 904 of window 902, One or more equipment can be waken up and consume power to monitor particular logical channel.Equally, one or more The power consumption of a equipment can be related to the paging size of part 904.Relatively large paging part 904 can increase power and disappear Consumption, and battery life can be reduced.In addition, the time associated with the paging part 904 of window 902 is sent indicates to divide The time of dispensing data portion 906.Therefore, when reducing the size for the paging part 904 for sending window 902 can allow more Between be used for data transmission.
In some cases, PWB 908 can be relatively flexible.It is, PWB 908 can indicate paging message Coboundary (that is, no paging message can be sent after PWB 908) in sending time.However, when detecting described seek When the free time of medium during the time being exhaled to be more than threshold duration, data transmission can be started.In specific implementation, competition Window parameter may be adjusted so that realization paging window edge flexibility.For example, a contention window parameter can be used for seeking Frame is exhaled, and another contention window parameter can be used for data frame.In some implementations, if for paging message and There are very small contention window sizes, the then paging message and ACK to obtain priority during the paging window by ACK, And it is much more quickly sent out than other transmission.If there are a large amount of sending devices during the paging window, described Paging message and ACK may occupy entire paging window, once and PWB 908 be hit, equipment just stops paging message It transmits and starts data transmission.If there are small amount of sending devices, the paging to disappear during the paging window Breath obtains priority, and the transmission of the paging message and the ACK are completed very fast during the paging window. In this case, there is " free time " during the paging window, and the equipment with data to be sent is competing The communication channel is striven, and starts to send out data during the paging window.
In some cases, the contention window size (or contention parameter) can be adapted so that paging notice have compared with Small competition size can quickly start to page notice, and if when having remaining after paging declaration Between, then can also during the paging window transmission data.For example, contention window parameter (" CW_paging ") can be with For paging frame, and another contention window parameter (" FixedCW_data_min, CW_data ") it can be used for data frame.For Transmission paging message, equipment can select Backoff window from [0, CW_paging].For transmission data, if equipment exists Starting to compete before PWB 908, then the equipment can select Backoff window from [FixedCW_data_min, CW_data], Wherein, FixedCW_data_min is more than CW_paging.As illustrative example and not restrictive, CW_paging can be 100, and FixedCW_data_min can be 101, and CW_data can be 1000.It is described in this illustrative aspect Equipment can select the first random number between 0 and 100 as the Backoff window for paging frame, and the equipment can be with needle The second random number between 101 and 1000 is selected to data frame.
As first exemplary example, equipment can start to compete the data biography at the beginning for sending window It is defeated, but if being not received by trigger frame before the Backoff window decrement, the equipment can be cancelled described Transmission.It is, being directed to each service announcement, the transmitter it is expected to confirm, for example triggers.If the transmitter does not have Receive the ACK, then the transmitter can not transmission data (without corresponding decrement for data).For example, As described above, if the transmitter provides the instruction to the availability for next N number of logic channel, and institute It states each of receiver and has been acknowledged the instruction, then there is the number of each for those receivers in the transmitter According to when, the transmitter can much start the data decrement in advance in the paging window, rather than always etc. Start just to start the decrement to the data window.
As second exemplary example, equipment can be sought after the transmitter receives the trigger frame described It exhales and starts competition data transmission during window.It is, the trigger frame indicates the ACK to the paging notice.With reference to wherein The exemplified earlier of the instruction to the availability for next 4 logic channels, the hair has been provided in the transmitter The machine of penetrating can not send out any paging notice, but the transmitter can be in data contention queue and with slightly higher Competition window.Equally, it is noticed once having completed to send with the paging notice other transmitters to be sent, then the transmitter It can start to send out data, because the transmitter starts to win the competition for the communication channel.The PWB contention windows Mouth (for example, CW_paging) can be with smaller, therefore decrement can quickly start so that paging notice prior to data Transmission.It is, by selecting CW sizes smaller compared to FixedCW_data_min, paging notice quilt for CW_paging Prior to data.At the beginning of the paging window, the transmitter that tool has data to send starts to associated contention window Mouth counts.
In the equipment in the case where starting competition after PWB 908, routine data contention parameter can be used, In, back-off parameter is selected from [0, CW_data].In the above example, for the competition after PWB 908, institute Stating equipment can select the random number between 0 and 1000 as the Backoff window.It is, if the paging window is gathered around very much It squeezes and there are a large amount of paging messages just sent during the paging window, then after PWB 908, equipment can make The communication channel is competed with routine data contention parameter.Therefore, in the paging window, data transmission can be opened in advance Begin, but the minimum value of the data contention during the paging window is being paged on the maximum value competed (for example, 101 arrive 1000).However.In the data window, competes the communication channel and start from the data window to be used for transmission data Beginning, and be continued until the competition boundary (for example, from 0 to 1000) of data transmission.
In another specific implementation, the type of service or class of service of paging message can be set to particular value with Preferentially to the transmission of paging message.For example, each type of message, for example, paging message, triggering message, data frame or its It, can have the traffic class field for the classification for indicating the message.For example, each message may include service quality (QoS) classification.The class of service (for example, QoS classifications) can indicate the priority of the message.Show as non-limiting Example, the class of service can have the value selected from high priority value, middle priority value and low priority value, and described Particular message can be by correspondingly preferential.In specific implementation, the class of service is the QoS classifications of value with definition (for example defined in IEEE or other industrial standardizations or by provider), and each value corresponds to different priority. For example, speech message can have QoS priority more higher than data-message.For priority paging message, equipment can generate Paging message with the highest priority value for the class of service.Triggering message can have more lower than paging message Priority, and data-message can have priority more lower than triggering message.It will be described by being based on the type of message Class of service is set as particular value, can the preferential paging message during paging window transmission.In addition, if other highers Priority message (such as paging message) is transmitted, then can be to enable the data transmission during the paging window.
With reference to figure 10, the exemplary diagram 1000 for sending window (TW) 1002 is instantiated.Figure 10 instantiates transmission window 1002 may include paging part 1004, triggering part 1006 and data portion 1008.Paging part 1004 can be paging window Mouthful, triggering part 1006 can be triggering window and data portion 1008 can be data window.It pages part 1004 and touches Hair part 1006 is separated by paging window edge (PWB) 1010 and triggering part 1006 and data portion 1008 are by triggering Window edge (TrWB) 1012 separates.In Fig. 10, triggering part 1006 indicates to be used for data sink seeking in response to data source It exhales message and sends the special period for triggering message to the data source.For example, the expression of triggering part 1006 is set for second Standby 106 send the period of PS-POLL message in response to the paging message 128 of Fig. 1 to the first equipment 104.
During paging part 1004, data source (such as first equipment 104 of Fig. 1) can be set to one or more subscribers Preparation send paging to notice.For example, the first equipment 104 can send paging notice to the second equipment 106.Triggering part 1006 indicates The period that notice is paged described in the triggering message back is utilized for subscriber device.However, in some cases, it is described to order Family equipment may be disabled.For example, the subscriber device can be operated just in low-power mode.Correspondingly, described to order Family equipment may not respond paging notice in the triggering window.Therefore, sending device can be based in institute It states in triggering window and whether receives the triggering message, it is determined whether be wake-up there are at least one receiver and can be used In reception data.If do not received in the triggering window (such as period between PWB 1010 and TrWB 1012) The triggering message, then the sending device can send window 1002 remainder in be transformed into low-power operation mould Formula.
In some implementations, the sequence that the receiving device sends trigger frame can be occurred based on the receiving device Sequence in the paging notice determines.In the case of TIM, the sequence can be determined by the bit sequence of AID.This A arrangement can reduce the triggering window between the receiver device for attempting to confirm the paging notice from the sending device In competition.In some cases, it is disabled in the first receiver device, may exist threshold time period, in institute After stating threshold time period, the second receiver device can be responded using trigger frame.It is, second receiver device First receiver device can be waited for confirm the paging notice in threshold time period, and if described first receives Machine equipment does not respond in the threshold time period, then second receiver device can send trigger frame.
A potential advantage associated with the transmission window 1002 illustrated in Figure 10 is that the size of the paging window can With relatively small.Since provider equipment can not possibly send paging notice, so the quantity that can send the equipment of paging notice can Can be limited, the subscriber device confirms the notice, but because too many equipment is being competed with announcement service, it is described to carry There is no time enough to send out data for quotient's equipment, while the data window is too small can not accommodate from all provider equipments Data transmission.As a contrast, in replacing arrangement, there may be keep waking up during sending window 1002 still sending out Send or receive multiple provider equipments of data.
As exemplary example, five equipment can send paging notice, and identify eight for each sending device A receiver device.However, the data window may be not enough large enough to accommodate 40 data transmissions.Therefore, reduce institute Stating the size of paging window can be advantageous.For example, three in five sending devices can connect to described eight It receives machine equipment and sends paging notice.24 ACK are received (that is, being directed to from all eight receiver devices however, substituting The ACK of three sending devices), 20 ACK can be received.In this case, it can be deposited in the data window In 20 data transmissions.It is, cannot confirm that the equipment of the notice may switch to low work(in the triggering window Rate operation mode, to save battery life.Therefore, only 20 receiving devices keep waking up and other 20 receptions are set It is standby to save battery life, rather than 40 equipment keep waking up and reduce battery life.
In some implementations, unused time associated with the triggering window can be re-requested to be used for Data transmission.For example, contention window parameter can be adjusted with the preferential ACK (such as PS-POLL message), while if Free time is detected during the trigger window, then data transmission is allowed to start before TrWB 1012.In specific implementation In mode, a contention window parameter (for example, " CW_Trigger ") can be used for trigger frame, and another contention window parameter (for example, " FixedCW_data_min, CW_data ") it can be used for data frame.In order to send triggering message, equipment can be from Backoff window is selected in [0, CW_Trigger].For transmission data, if equipment starts to compete before TrWB 1012, The equipment can select Backoff window from [FixedCW_data_min, CW_data], wherein FixedCW_data_min More than CW_Trigger.
In addition, in some implementations, unused time associated with the paging window can be re-requested To be used to trigger message transmission.For example, a contention window parameter (for example, " CW_paging ") can be used for paging frame, and it is another One contention window parameter (for example, " FixedCW_Trigger_min, CW_Trigger ") it can be used for trigger frame.In order to send out Send paging message, equipment that can select Backoff window from [0, CW_paging].In order to send triggering message, if equipment exists Start to compete before PWB 1010, then the equipment can select back from [FixedCW_Trigger_min, CW_Trigger] Move back window, wherein FixedCW_Trigger_data_min is more than CW_paging.
Transmitter can send notice in advance, and no matter they, which are available, is also disabled, but receiver may not With this ability.Therefore, in some implementations, since the availability of specific receiver is not before an ack is received Know, therefore the equipment with the business for multiple recipients can be by notifying several receptions during the paging window Machine carrys out overbooking or excess is subscribed to.For example, transmitter, which can predefine data transmission period, can allow five The transmission of receiver.However, the transmitter possibly can not determine in five receivers each be available or can not .Therefore, if transmitter has for the business more than five receivers (for example, ten receivers), the transmitting Machine can be to this all ten receiver announcement services.Then, the transmitter can wait in described ten receivers to be determined How many utilization trigger frame responds.Then, the transmitter can be just for five or the reception in the receiver Eight scheduling business in machine, depend on that how many receiver is responded using trigger frame.If the transmitter is only to described Five notice business (known capacity for sending window based on the data) in receiver, and in the only described receiver Three are noticed using described in triggering frame acknowledgment, then can exist and underuse the data window.
In some cases, be paged equipment can by send PS-POLL message, QoS Null frames or via some its Its mechanism is responded during the triggering window.Each triggering message can be confirmed in the transmitter.However, if touching The quantity for sending out message is more than particular value, then the transmitter can not confirm additional triggering message.For example, the transmitter can It is not enough to each equipment transmission data into the multiple equipment for sending triggering message with the determination size for sending window.Institute Stating transmitter can be not enough to based on the determination size for sending window to each equipment transmission data for sending triggering message, The one or more of triggering message are sent to confirm.For example, the transmitter can be confirmed to every in the triggering message The reception of a triggering message, but the not transmission data during the data window.In another example, the transmitter can With confirm to from during the data window data will be sent to the reception of the triggering message of the receiver of data, and And do not confirm the triggering message from the receiver that will not be sent to data during the data window.Show at another In example, the reception to each of triggering message triggering message can be confirmed in the transmitter, and can be described true To specific receiver transmission data during instruction will not be in the data window in some confirmations recognized.For example, To in the confirmation of the triggering message from specific receiver, the value of a bit of the confirmation can be set to described specific Receiver instruction does not have data to the value that the specific receiver is sent to during the data window.Refer in response to receiving Show the confirmation of transmission data during will not be in the data window, or in response to being not received by special time period really Recognize, the receiver may switch to whether low-power operating mode or the receiver can be the receptions according to this The unique transmitter that machine is waiting for participates in some other network.
With reference to figure 11, the service discovery frame (SDF) 1100 including having the attribute for being paged list of devices (PDL) is shown Exemplary diagram.In specific implementation, SDF 1100 may include or corresponding to Fig. 1 paging message 128.SDF 1100 may include header fields (such as frame check (FC) field), Duration field, address field A1, A2 and A3, sequence Control (seq.ctl.) field, timestamp field, beacon interval field, capable field, Frame Check Sequence (FCS) field or they Combination.In some implementations, as described with reference to fig. 1, the A1 fields can have specific receiver address The receiver address field of value 170.In addition, the A3 fields can indicate NAN clusters ID.In specific receiver address value 170 Be the NAN clusters ID specific implementation in, the A1 fields and the A3 fields having the same can be worth.

The instruction provided by the first bit set 1220 is illustrated, if the first bit set 1220 is specific with first Value, then the data being scheduled to be transmitted by the equipment for sending the message for including paging attribute 1200 are multi-case datas.In spy Determine in realization method, if the data are multi-case datas, PDL 1210 can not be included in paging attribute 1200.At this In kind situation, receiving each equipment for the message for including paging attribute 1200 can be based on detecting paging control field 1208 the first bit set 1220 has the first particular value, is maintained in active operation mode.If the first bit set 1220 have the second particular value, then the data can be unicast data, and PDL 1210 can be indicated by TIM.If the One bit set 1220 has third particular value, then the data can be unicast data, and PDL 1210 can be by Bloom Filter indicates.If the first bit set 1220 has the 4th particular value, the data can be unicast data, and PDL 1210 can be indicated by MAC Address list.If the first bit set 1220 has the 5th particular value, the first sets of bits It closes 1220 instructions and generates new public packet key (CGK) via the equipment of the data link group.In this case, The MAC Address (or other identifiers) of equipment of the PDL 1210 including generating the CGK, and if type of service indicator 1212 are included in paging attribute 1200, then type of service indicator 1212 indicates highest priority traffic type.For example, business Type indicator 1212 can indicate highest QoS classifications corresponding with the business.
PDL 1210 can have variable-size, and can indicate the equipment for being scheduled as receiving business from particular device Subset.PDL 1210 can be indicated by TIM, Bloom filter or MAC Address list.PDL 120 can be identified to be retouched with reference to figure 1 Each equipment in the subset of devices stated.
Service announcement attribute 1230 may include attribute ID field 1232.Service announcement attribute 1230 may include length word Section 1234 comprising identification service notices the value of the length of attribute 1230.Service announcement attribute 1230 can also include data-link Road group id field 1236 comprising identify the value of the data link group.It is paging by message identifier in specific implementation The specific receiver address value of message can be the value of data link group id field 1236.Data link group id field 1236 also may be used With referred to as NDL identifiers.
Service announcement attribute 1230 further includes PDL 1238.PDL 1238 can be indicated by type lengths values (TLV) field. The type field of the TLV fields can indicate the type of PDL 1238, such as TIM, Bloom filter or MAC Address list. The length field of the TLV fields can indicate the length of the value field of the TLV fields.The value field includes equipment row Table.In some implementations, service announcement attribute 1230 further includes type of service indicator, instruction be scheduled for The type of the business of equipment transmission in PDL 1238.
Therefore, Figure 12 illustrations may include being scheduled as reception business in frame (such as SDF or management frame) with instruction Two attributes of list of devices.If the business of more than one type is scheduled for transmitting, the frame may include multiple Attribute, and each attribute in the multiple attribute corresponds to different types of business.For example, the frame may include multiple Paging attribute 1200 or multiple service announcement attributes 1230.The equipment for receiving the frame can handle the multiple attribute, with true Determine the type whether business is scheduled for the business transmitted and be scheduled.
With reference to figure 13, a kind of specific implementation of operating method is shown and is generally designated as 1300.In specific reality In existing mode, method 1300 can be by the offer of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 Quotient's logic 130 executes.
Method 1300 is included at 1302, during the connection establishment stage of the communication of NAN (or find window phase in NAN Between), from the second equipment availability of reception information at the first equipment.The connection establishment stage includes to device capability information It exchanges.For example, with reference to figure 1, the first equipment 104 (for example, provider equipment) can be in the association phase phase of the communication of NAN 102 Between, from 106 (for example, subscriber device) availability of reception information 116 of the second equipment, the association phase includes to ability information 114 exchange.In some implementations, the connection establishment stage includes association phase.It is described in other realization methods It includes negotiation phase to connect establishment stage.In specific implementation, institute is added in the second equipment 106 during the association phase Data link group is stated, and the data link group includes the first equipment 104 and one or more of the other equipment.
Method 1300 is included at 1304, and transmission includes the paging message of service indicator during paging window.It is described Second device identification is to be scheduled as receiving data by service indicator.For example, with reference to figure 1, the first equipment 104 can paged During window paging message 128 is sent to the second equipment 106.Paging message 128 may include by the second equipment 106 be identified as by It dispatches to receive the service indicator of data.As non-limiting example, the service indicator may include that business instruction is reflected Penetrate the hash of (TIM), Bloom filters, media access control (MAC) address list, Section MAC address list or MAC Address List.
Method 1300 is included at 1306, be based on the available information, it is determined whether during sending window to second Message exchange is executed before equipment transmission data with the availability of determination second equipment.For example, with reference to figure 1, the first equipment 104 can be based on the availability information 116 received from the second equipment 106 during the association phase, it is determined whether It sends during window to before the second equipment transmission data 122, waits for from the second equipment 106 and receive trigger frame 182.As another Example, with reference to figure 1, the first equipment 104 can be based on availability information 116, it is determined whether by sending PS-POLL message, clothes Quality (QoS) NULL message of being engaged in (or service quality (QoS) NULL frames), ATIM message, action action frame or another unicast messages come true The availability of fixed second equipment.In some implementations, data 122 can be sent during data window.Other In realization method, data 122 can be sent before data window starts, such as during paging window or in triggering window phase Between.
In specific implementation in figure 13 illustrates, method 1300 is included at 1308, in response to determination (described Received during the association phase of NAN) availability information indicate second equipment the NAN data link group Transmission window during be available, during the transmission window from first equipment to second equipment send described in Data, without executing message exchange with the availability of determination second equipment.For example, with reference to figure 1, availability information 116 can To provide the data that exclusively can be used for (for example, " always " can be used for) NAN 102 to the second equipment 106 to the first equipment 104 The instruction of communication during window, and the first equipment 104 can to 106 transmission data 122 of the second equipment (in the transmission During window) before, forbid execute message exchange with determine the second equipment 106 availability (such as via polling mechanism or touch Hair mechanism).
Figure 13 is also illustrated, and does not indicate second equipment in the transmission window in response to the determination availability information The availability of period, method 1300 may include, and at 1310, message exchange is executed before sending the data to determine The second equipment is stated to be available.For example, with reference to figure 1, availability information 116 can provide instruction, the finger to the first equipment 104 Show be data link group to the second equipment 106 and not exclusively for (for example, not being that " always " can be used for) NAN 102 transmission The instruction of communication during window, or the second equipment 106 " preference " is polled and is utilized in the transmission window Period receives the instruction that the instruction of the availability of data 122 is responded.In this case, the first equipment 104 can be with poll Second equipment 106, and the response from the second equipment 106 can be waited for before transmission data 122.As another example, Second equipment 106 can provide instruction, and the instruction is to send trigger frame to the second equipment 106 " preference " to provide to described The instruction of the instruction of the availability of data 122 is received between transmission window phase.
In specific implementation, the availability information may include the specific fields for having individual bit, and institute The value for stating specific fields indicates whether second equipment is available during the data window of the data link group of the NAN 's.For example, the instruction 162 of Fig. 1 can via instruction 162 in specific bit bit value come identify dedicated availability (or Unavailability).Additionally or alternatively, the availability information may include the specific bit field for having multiple bits, And the value of the specific bit field indicates second equipment corresponding with including the data link group of the first equipment Each data window during whether be available.For example, the availability information 116 of Fig. 1 can be include multiple bits and The field of instruction corresponding with " always " available mode, " preference is polled " state or " preference transmission trigger frame " state is provided.
Therefore, instantiate can be based on the availability provided during the association phase of the communication of the NAN by Figure 13 Information reduces the messaging service during the transmission window of the NAN.In fig. 13, if subscriber device is provided to described Subscriber device is available instruction during the data window of the data link group of the NAN, then provider equipment can forbid Message exchange is executed with the availability of the determination subscriber device, so as to cause messaging service (such as with polling message or triggering The associated business of frame) it reduces.Replace, the provider equipment can send include (during paging window) will be described Subscriber device is identified as the paging message of the service indicator of the recipient of data, and can send the data (in number According to during window) before, forbid executing message exchange with the availability of determination second equipment.
With reference to figure 14, a kind of specific implementation of operating method is shown and is generally designated as 1400.In specific reality In existing mode, method 1400 can be by the subscriber of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 Logic 134 executes.
Method 1400 is included at 1402, during the connection establishment stage of the communication of NAN (or find window phase in NAN Between), send availability information from the first equipment to the second equipment.The connection establishment stage includes the friendship to device capability information Change, and the availability information indicate first equipment during the transmission window of the data link group of the NAN can The property used.For example, with reference to figure 1, the second equipment 106 (for example, subscriber device) can be in the association phase of the communication of the NAN 102 Period sends availability information 116 to the first equipment 104 (for example, provider equipment), and the association phase includes believing ability The exchange of breath 114.In some implementations, the connection establishment stage includes association phase.In other realization methods, institute It includes negotiation phase to state connection establishment stage.
Method 1400 is included at 1404, during paging window, is connect from second equipment at first equipment Receive paging message.It is the service indicator for being scheduled as receiving data that the paging message, which includes by first device identification,. For example, with reference to figure 1, the second equipment 106 can receive paging message 128 during paging window from the first equipment 104.Paging disappears Breath 128 may include being identified as the second equipment 106 to be scheduled to receive the service indicator of data.Show as non-limiting Example, the service indicator may include traffic indication map (TIM), Bloom filters or the address media access control (MAC) List.
Figure 14 is also illustrated indicates first equipment in the data link group in response to the determination availability information Transmission window during be available, method 1400 may include, and at 1406, forbid executing message exchange with to described second Equipment provides the instruction to availability.For example, with reference to figure 1, in response to determining the availability information 116 for the second equipment 106 Indicate that the second equipment 106 is available during the transmission window of the data link group of the NAN, the second equipment 106 can prohibit Only sent to the first equipment 104 to the instruction of availability (for example, to polling message or trigger frame from the first equipment 104 Response).It is not that instruction first equipment is available during the transmission window in response to the determination availability information, Method 1400 may include, and at 1408, execute message exchange to provide the instruction to availability to second equipment.Example Such as, with reference to figure 1, if being directed to the availability information 116 of the second equipment 106 without indicating the second equipment 106 in the transmission window Availability during mouthful, the then instruction that the second equipment 106 can be to the transmission of the first equipment 104 to availability.
In the specific implementation illustrated in fig. 14, method 1400 can also include, at 1410, in the transmission window During mouthful, data are received from second equipment at first equipment.For example, with reference to figure 1, second is directed in response to determining The availability information 116 of equipment 106 indicates that the second equipment 106 is available during the data window of the data link group, Second equipment 106 can receive data during the transmission window from the first equipment 104, without executing message exchange with to the Two equipment 106 provide the instruction to availability.In some implementations, the second equipment 106 can during data window from First equipment 104 receives the data.In other realization methods, the second equipment 106 can start it in the data window Before (such as during paging window or during triggering window), receive the data from the first equipment 104.
In specific implementation, method 1400 can also include being executed during the connection establishment stage and described the The association of two equipment.For example, with reference to figure 1, institute can be added in the second equipment 106 during the association phase of the communication of NAN 102 Data link group is stated, the association phase includes the exchange to ability information 114.Additionally or alternatively, the availability Information may include specific fields or specific bit value, and the value of the specific fields or the specific bit value can indicate Whether second equipment is available during the transmission window.For example, the instruction 162 of Fig. 1 can be via in instruction 162 Specific fields or the bit value of specific bit identify special availability (or unavailability).Additionally or alternatively, institute It may include the specific bit field for having multiple bits to state availability information, and the value of the specific bit field indicates institute State whether the second equipment is available during each data window of the data link group including first equipment.For example, The availability information 116 of Fig. 1 can be included multiple bits and provide and " always " available mode, " preference is polled " state Or the field of " preference transmission trigger frame " corresponding instruction of state.
Therefore, instantiate can be based on the availability provided during the association phase of the communication of the NAN by Figure 14 Information reduces the messaging service during the transmission window of the NAN.In fig. 14, subscriber device can be in the association phase Period provides the instruction to availability.It includes by the subscriber device mark that provider equipment, which can be sent (during paging window), Know be data recipient service indicator paging message, and the subscriber device can forbid execute message exchange with The instruction that the availability for receiving data during the data window to the subscriber device is provided, so as to cause messaging service (such as business associated with the response to polling message or trigger frame) is reduced.
With reference to figure 15, a kind of specific implementation of operating method is shown and is generally designated as 1500.In specific reality In existing mode, method 1500 can be by the offer of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 Quotient's logic 130 executes.
Method 1500 includes, and at 1502, generation includes to first equipment in special time period at the first equipment It inside whether is available the message of instruction, during the special time period, in the data link group of neighbours' sensing network (NAN) Equipment be configured as operating in active operation mode.For example, with reference to figure 1, provider's logic 130 of the first equipment 104 can With generating beep-page message 128 or service advertisement 120, and paging message 128 or service advertisement 120 can indicate the first equipment 104 are available in special time period.
Method 1500 further includes, at 1504, from first equipment to one or more of described data link group Equipment sends the message.For example, with reference to figure 1, the first equipment 104 can send paging message 128 to the second equipment 106, or The first equipment of person 104 can send service advertisement 120 to the second equipment 106 and third equipment 108.

Expire and sought to the transmission of one or more of equipment in addition, method 1900 may be responsive to first decrement Message is exhaled, and expires in response to second decrement and sends the data service.Additionally or alternatively, described Paging message may include the first traffic class field, and the data frame of the data service may include the second class of service Field.In oneainstance, the value of first traffic class field correspond to than second traffic class field value more High priority.For example, with reference to figure 9, paging message may include the first traffic class field, first traffic class field With the higher priority of the second traffic class field for including than the data frame.In addition, the first service class malapropism Section and second traffic class field may include service quality (QoS) classification field.In another specific implementation, side Method 1900 may include the transmission data during triggering window, as further described with reference to figure 21.
With reference to figure 20, a kind of particular aspects of operating method are shown and are generally designated as 2000.In specific implementation side In formula, method 2000 can be by subscriber's logic of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 134 execute.In some cases, if what is received from particular device during the association phase of the communication of NAN 102 is available Property information 116 indicates the communication during the particular device " always " not can be used for data window, then can execute method 2000。
Method 2000 includes, at 2002, during first time period, in the data link of neighbours' sensing network (NAN) Specific communication channel corresponding with the data link group is monitored at the second equipment in group.Particular logical channel can indicate or Corresponding to the special time period and the particular logical channel.For example, with reference to figure 1, the second equipment 106 can be used as and order The subscriber device operation of service is read, and the first equipment 104 may be provided as service provider's operation of special services.It is described Particular logical channel can indicate the logic cited in the index by logic channel associated with the data link group One of channel, as further described relative to Fig. 2.Subscriber's logic 134 of second equipment 106 specific can be patrolled with described During collecting the corresponding paging window of channel, the specific communication channel is monitored.
Method 2000 further includes, and at 2004, is connect from the first equipment corresponding with special services at second equipment Receive paging message.For example, with reference to figure 1, subscriber's logic 134 of the second equipment 106 can receive paging message from the first equipment 104 128.In some implementations, the paging message includes being directed to next N number of logic channel to the provider equipment Availability instruction.E.g., including the instruction 162 in paging message 128 is indicated to the first equipment 104 under described connect The instruction of the availability of the N number of logic channel 164 come.It is, the paging message 128 illustrated in Fig. 1 can be indicated via institute Paging (business) notice of particular logical channel is stated, and the instruction 162 to availability can be indicated in the data-link The other logic channels followed after the particular logical channel in the index of the logic channel of road group.
As illustrative example and not restrictive, with reference to figure 4, subscriber's logic 134 of the second equipment 106 can with it is basic During the 322 associated paging window of transmission window 324 of communication channel 306, paging message 128 is received.It is, can be Paging message is received between paging window phase associated with the basic communication channel cited in the index by the logic channel 128, as relative to described in Fig. 2.Alternatively, as relative to described in Fig. 5-8, can with the index institute by logic channel Paging message 128 is received between the associated paging window phase of one of the complement channel of reference.For example, with reference to figure 5 and figure 7, subscriber's logic 134 of the second equipment 106 can page 332 period of window sending window 328 associated first with first Or 336 period of window is paged sending window 330 associated second with the second of the first complement channel 308, it receives paging and disappears Breath 128.As another example, with reference to figure 6 and Fig. 8, subscriber's logic 134 of the second equipment 106 can send window with first During 340 associated first paging windows 344 or associated with the second of the second complement channel 310 the transmission window 342 During second paging window 348, paging message 128 is received.
Method 2000 further includes sending and confirming from second equipment to first equipment, such as power at 2006 Save poll (PS-POLL) message.For example, with reference to figure 1, subscriber's logic 134 of the second equipment 106 can be to the first equipment 104 It sends and confirms.Method 2000 further includes, and at 2008, institute corresponding with the data link group is monitored at second equipment State the first logic channel in multiple logic channels.Method 2000 can also include, and at 2010, believe with first logic Before the corresponding data window in road starts, data service is received from first equipment at second equipment.In some realities In existing mode, the data service can be received during at least part of paging window.It, can be in other realization methods The data service is received during at least part of triggering window.It, can be in paging window phase in other realization methods Between receive the paging message, and method 2000 may include during the paging window and the data window it Preceding transmission trigger frame.For example, each frame can be sent with priority orders so that paging message is highest priority, is touched The priority that frame is lower than paging message is sent out, and data frame is the priority lower than trigger frame.It is, for example, possible to use competition window Value controls the priority of each frame.In another example, the priority of each frame can be controlled using class of service.
For example, with reference to figure 3, subscriber's logic 134 of the second equipment 106 can be in the hair with basic communication channel 306 During sending 322 associated paging window of window 324, ACK is sent to the first equipment 104.In this illustration, the logic letter First logic channel cited in the index in road can be the first complement channel 308.As reference chart 20 herein uses , " first " logic channel, which can not be the logic that the ordinal number cited in the index by the logic channel is first, to be believed Road.Therefore, the second equipment 106 can be during sending the associated first paging window 332 of window 328 with first, monitoring the One complement channel 308.In addition, the second equipment 106 can receive data during the first paging window 332 from the first equipment 104 Business.Therefore, the instruction to availability received from the first equipment 104 during paging window 324 can allow with the One logic channel carries out data transmission during the associated paging part for sending window.For example, the data transmission can be sent out Raw 332 period of the first paging window that window 328 is sent associated with the first complement channel 308 first.
As another example, with reference to figure 3, subscriber's logic 134 of the second equipment 106 can with the first complement channel 308 First send during window 328 associated first pages window 332, send ACK to the first equipment 104.In such case In, the first logic channel cited in the index of the logic channel can be the second complement channel 310.Next logic channel It can indicate to follow next complement channel after the first complement channel 308 in the index of the logic channel.Therefore, Second equipment 106 can send the second complement channel of associated first paging window, 344 period monitoring of window 340 with first 310.In addition, the second equipment 106 can receive data service during the first paging window 344 from the first equipment 104.
As another example, with reference to figure 3, subscriber's logic 134 of the second equipment 106 can with the second complement channel 310 First send during window 340 associated first pages window 334, send ACK to the first equipment 104.In such case In, the first logic channel cited in the index of the logic channel can be the first complement channel 308.Therefore, the second equipment 106 can send the first complement channel 308 of associated second paging window, 336 period monitoring of window 330 with second.This Outside, the second equipment 106 can receive data service during the second paging window 336 from the first equipment 104.
As another example, with reference to figure 3, subscriber's logic 134 of the second equipment 106 can with the first complement channel 308 Second send during window 330 associated second pages window 336, send ACK to the first equipment 104.In such case In, the first logic channel cited in the index of the logic channel can be the second complement channel 310.Therefore, the second equipment 106 can send the second complement channel 310 of associated second paging window, 348 period monitoring of window 342 with second.This Outside, the second equipment 106 can receive data service during the second paging window 348 from the first equipment 104.
In specific implementation, method 2000 further includes:Before receiving the paging message, joined based on the first competition Number starts the first decrement during specific paging window, and based on the second contention parameter in the specific paging window phase Between start the second decrement.In at least one realization method, second contention parameter corresponds to than first competition The parameter longer period.For example, with reference to figure 9, first decrement can be started based on parameter CW_paging, And second decrement can be started based on parameter FixedCW_data_min.FixedCW_data_min correspond to than Period longer CW_paging.Method 1900 may be responsive to first decrement and expire and be sought second Message is exhaled to be sent to the miscellaneous equipment of the data link group from second equipment, and in response to second decrement Expire and third equipment the second data service of transmission into the data link group.Second paging message can be described It is sent during specific paging window, and second data service can be sent before the second data window starts.
Additionally or alternatively, the paging message may include the first traffic class field, and the data industry The data frame of business may include the second traffic class field.In oneainstance, the value of first traffic class field corresponds to In the higher priority of value than second traffic class field.For example, with reference to figure 9, paging message may include the first industry Business classification field, first traffic class field have more higher than the second traffic class field that the data frame includes Priority.In addition, first traffic class field and second traffic class field may include service quality (QoS) class Malapropism section.
In another specific implementation, method 2000 includes:During the second period, it is supervised at second equipment The specific communication channel is surveyed, and the second paging is received from third equipment corresponding with second service at second equipment Message.Second paging message can connect during the paging window portion for sending window corresponding with the second time period It receives.Method 2000 can also include:During the triggering window portion for sending window, by trigger frame from second equipment It is sent to the third equipment, and during the triggering window portion for sending window, from institute at second equipment It states third equipment and receives data service.Method 2000 can also include:During the data service part for sending window, At second equipment data service is received from the third equipment.It is further described with reference to figure 22 indirect in triggering window phase Receive data.In some implementations, the second time period corresponds to specific cited in the index by the logic channel Logic channel, as with reference to described in figure 3.
Therefore, Figure 20 is instantiated during specific paging window from provider equipment (such as first equipment 104 in Fig. 1) What is received can allow the first logic channel cited in the index with logic channel associated the instruction of availability Data transmission is carried out during the follow-up paging part for sending window.Data transmission during the paging part for sending window can To improve data throughout because data transmission can not only be allowed to it is described send window the data portion during into It goes but also can be allowed to carry out during the paging part.
With reference to figure 21, a kind of particular aspects of operating method are shown and are generally designated as 2100.In specific implementation side In formula, method 2100 can be patrolled by the provider of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 130 are collected to execute.In some cases, if what is received from particular device during the association phase of the communication of NAN102 is available Property information 116 indicates the communication during the particular device " always " not can be used for data window, then can execute method 2100。
Method 2100 includes, and at 2102, during the paging window portion for sending window, is generated at provider equipment Paging message.For example, with reference to figure 1, provider's logic 130 of the first equipment 104 can be in the paging window portion for sending window Period generating beep-page message 128.For example, as relative to described in Figure 10, provider's logic 130 of the first equipment 104 It can indicate seek in the paging part 1004 period generating beep-page message 128 for sending window 1002, the paging part 1004 Exhale the period before the PWB 1010 that part 1004 and triggering part 1006 separate.
Method 2100 further includes, and at 2104, the paging message is sent to neighbours' perception from the provider equipment One or more of the data link group of network (NAN) subscriber device.For example, with reference to figure 1, the first equipment 104 can be to NAN At least the second equipment 106 in 102 sends paging message 128.In addition, in some cases, multiple equipment can be subscribed to by The special services that one equipment 104 provides.For example, third equipment 108 can indicate that subscribing to the another of the special services sets It is standby.In this case, the first equipment 104 can also send paging message 128 to the third equipment 108 of NAN 102.
Method 2100 includes, and at 2106, is determined at the provider equipment and is following seeking in the transmission window During the triggering window portion for exhaling the transmission window after window portion, if set from one or more of subscribers Each standby receives confirmation, for example triggers message.For example, provider's logic 130 (see Fig. 1) of the first equipment 104 can be with It determines during sending the triggering part 1006 of window 1002, if receive ACK from each of described subscriber device (see Figure 10).For example, in the second equipment 106 of Fig. 1 indicates the simplification situation of the single subscriber device on NAN 102, First equipment 104 can determine during sending the triggering part 1006 of window 1002, if be connect from first equipment Receive the triggering message.As another example, in Fig. 1 the second equipment 106 and third equipment 108 indicates that multiple subscribers set In the case of standby, the first equipment 104 may determine whether to receive from each of the second equipment 106 and third equipment 108 To triggering message.
If receiving institute from one or more of subscriber devices during the triggering window portion for sending window ACK is stated, for example triggers message, then method 2100 may include:At 2108, the triggering window portion in the transmission window At least part during transmission data business.For example, provider's logic of the first equipment 104 can send window 1002 During at least part of triggering part 1006, to 108 transmission data 122 of the second equipment 106 and/or third equipment.As relatively It is further described in Figure 10, contention window parameter can be used to allow occurs data transmission before TrWB 1012.
In addition, method 2100 includes:At 2110, following after the triggering window portion for sending window The transmission window data portion during transmission data business.For example, provider's logic of the first equipment 104 can sent out During the data portion 1008 for sending window 1002, to 108 transmission data 122 of the second equipment 106 and/or third equipment.
If received from one or more of subscriber devices during the triggering window portion for sending window To the ACK, for example message is triggered, then method 2100 is directly to the transmission data business at 2110.It is, data industry Business can be in the data portion for following the transmission window after the triggering window portion for sending window Period sends.As further described relative to Figure 10, TrWB 1012 can indicate the threshold amount of time of ACK to be received, And in the case where not receiving ACK from each of one or more of subscriber devices, window 1002 is being sent Data transmission can not occur during triggering part 1006.
Therefore, it can include not only paging part that Figure 21, which is instantiated and sent window (such as transmission window 1002 in Figure 10), It can also include triggering part.The triggering part can be used for receiving ACK from subscriber device.If in the transmission window ACK is received from each of one or more of subscriber devices during triggering part, then in the triggering for sending window Data transmission can occur during part.Data transmission during the triggering part for sending window can improve data throughput Amount can also be allowed to because data transmission is not only permitted to carry out in the data portion for sending window in institute It states in triggering part and carries out.
With reference to figure 22, a kind of particular aspects of operating method are shown and are generally designated as 2200.In specific implementation side In formula, method 2200 can be by subscriber's logic of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 134 execute.In some cases, if what is received from particular device during the association phase of the communication of NAN 102 is available Property information 116 indicates the communication during the particular device " always " not can be used for data window, then can execute method 2200。
Method 2200 includes:At 2202, monitored at the subscriber device of the data link group of neighbours' sensing network (NAN) Particular logical channel in multiple logic channels associated with the data link group.For example, the subscriber of the second equipment 106 patrols Volumes 134 can monitor the particular logical channel in multiple logic channels associated with the data link group of NAN 102 150.
Method 2200 further includes:At 2204, set from provider associated with special services at the subscriber device It is standby to receive paging message.The subscriber device can be in the paging window for sending window associated with the particular logical channel The paging message is received during part.For example, subscriber's logic 134 of the second equipment 106 can be believed with the certain logic Paging message 128 is received during the associated paging window portion for sending window in road.Such as further described relative to Fig. 3-8 , it can be during paging window associated with basic communication channel 306 324, associated with the first complement channel 308 During first paging window 332 or second pages window 336, or in first paging window associated with the second complement channel 310 During mouth 344 or the second paging window 348, paging message 128 is received.
Method 2200 further includes:At 2206, the transmission window after the paging window portion is being followed During triggering window portion, sends and confirm from the subscriber device to the provider equipment, for example trigger message.For example, the Subscriber's logic 134 of two equipment 106 can follow during the triggering window portion after the paging window portion to the One equipment 104 (see Fig. 1) sends ACK.For example, can follow in Fig. 10 transmission window 1002 paging part 1004 it During the triggering part 1006 of transmission window 1002 afterwards, ACK is sent to the first equipment 104.
Method 2200 can also include:At 2208, during the triggering window portion for sending window, in institute It states and receives data service from the provider equipment at subscriber device.For example, subscriber's logic 134 of the second equipment 106 can be Data service is received during the triggering window portion for sending window.For example, the second equipment 106 can be in Figure 10 In transmission window 1002 triggering part 1006 during receive data 122.As further described relative to Figure 10, TrWB 1012 can indicate the threshold amount of time for the ACK to be received by provider equipment (such as first equipment 104), and if from institute Each for stating one or more subscriber devices receives ACK, then can be during sending the triggering part 1006 of window 1002 Data transmission occurs.
Method 2200 can also include:At 2210, the transmission window after the triggering window portion is being followed During the data service part of mouth, data service is received from the provider equipment at the subscriber device.For example, second sets Standby 106 subscriber's logic 134 can receive data service during the data portion 1008 of the transmission window 1002 of Figure 10, such as Data 122.
With reference to figure 23, a kind of particular aspects of operating method are shown and are generally designated as 2300.In specific implementation side In formula, method 2300 can be patrolled by the provider of at least one of equipment 104,106,108 and 110 in the system 100 of Fig. 1 130 are collected to execute.In some cases, if what is received from particular device during the association phase of the communication of NAN 102 can The communication during the particular device " always " not can be used for data window is indicated with property information 116, then can execute method 2300。
Method 2300 includes:At 2302, in the group (for example, data link group) of neighbours' sensing network (NAN) Generating beep-page message at one equipment.For example, the first equipment 104 (via provider's logic 130) can be with generating beep-page message 128. The paging message includes being paged list of devices.The subset of devices for being paged list of devices and identifying described group.It is described to set Standby subset is scheduled as receiving data from first equipment during sending window.The paging message includes having specific connect The receiver address field of receipts machine address value.For example, paging message 128 may include identifying setting for the data link group The PDL 174 of standby subset.The subset of devices can be scheduled as receiving data 122 from the first equipment 104.In addition, paging disappears Breath 128 may include the receiver address field with specific receiver address value 170.In specific implementation, the spy Determine receiver address value to be stored in the memory of first equipment.For example, specific receiver address value 170 can be deposited Storage is in the memory of equipment 104,106,108 and 110.In another specific implementation, the specific receiver address value includes NAN cluster ID related with the NAN.For example, specific receiver address value 170 can be by the A3 words of the SDF 1100 of Figure 11 The NAN clusters ID that segment table shows.In another specific implementation, the specific receiver address value includes related with described group Group identifier, such as data link group identifier related with data link group.For example, specific receiver address value 170 can be with It is data link group id field 1126.In another specific implementation, the specific receiver address value is by electrical and electronics Association of Engineers (IEEE) standard, Wi-Fi Alliance standard or the two definition.
Method 2300 further includes during paging window at least one other than first equipment in described group A equipment sends the paging message.For example, the first equipment 104 can be during the paging window of the data link group to Two equipment 106 and third equipment 108 send paging message 128.It is scheduled for the number if the first equipment 104 has The data of one or more of equipment according to link group transmission, then can send paging message 128.
In specific implementation, method 2300 includes in response to sending the paging message from described group second Equipment, which receives, to be confirmed.For example, in response to sending paging message 128, the first equipment 104 can be from the second equipment 106 (or from third Equipment 108) receive ACK 180.The confirmation can be received after short interFrameGap (SIFS) period.In addition, described Two equipment can be different from the subset of devices.For example, the first equipment 104 can receive ACK 180 from third equipment 108, i.e., Third equipment 108 is set to be not included in the subset of devices indicated by paging message 128.
In specific implementation, method 2300 includes from described group multiple in response to sending the paging message Equipment receives multiple confirmations.In addition, as described with reference to fig. 1, if the multiple equipment is given birth to based on identical Scrambling seeds At the multiple confirmation, then the multiple confirmation can be with waveform having the same, and can be received as multiplexing.Or Person, method 2300 may be responsive to reception wave type energy of the detection more than threshold value, detect the reception to multiple confirmations. The detection reception wave type energy in short interFrameGap (SIFS) period, and can be based on different Scrambling seeds to generate State multiple confirmations.For example, as described with reference to fig. 1, the first equipment 104 can monitor nothing during the SIFS periods Gauze network, to detect transmission energy level corresponding with multiple ACK waveforms.When detecting the transmission energy level more than threshold value When, the transmission energy level can be construed to the instruction to receiving multiple ACK waveforms by the first equipment 104.Based on described Sending energy level can enable the first equipment 104 to detect multiple ACK the reception of multiple ACK to detect, even if described Multiple ACK cannot be decoded due to the interference from multiple ACK.
